Distributor Mounting Clamp for 123Ignition Distributor 

Securely install a 123Ignition distributor into a Porsche 356 or 912 3-piece engine case with this upgraded OE Match Aluminium Distributor Mounting Clamp.

Fits:

• Porsche 912 SWB 1965-1968 (F)
• Porsche 356 1950-55
• Porsche 356A 1955-59
• Porsche 356B 1959-63
• Porsche 356C 1963-65

Specifically designed for use with a 123Ignition distributor, this mounting clamp replaces the original thin 2mm distributor clamp and separate spacer ring arrangement. Its wider 9mm clamping surface provides improved support and more even pressure distribution around the distributor.

The design also helps ensure that the distributor sits at the correct height and rests properly against the engine housing, preventing it from being installed too deeply and incorrectly loading against the distributor drive shaft.

What Does the Distributor Mounting Clamp Do?

The distributor mounting clamp secures the distributor in its correct position within the engine case.

Once the ignition timing has been set, the clamp holds the distributor securely so it cannot rotate or move during engine operation.

When installing a 123Ignition distributor into a classic Porsche 356 or 912 engine, correct positioning is particularly important. The distributor needs to sit at the correct depth within the housing while engaging correctly with the distributor drive.

This upgraded clamp helps:

• Secure the 123Ignition distributor correctly
• Maintain the correct distributor installation height
• Distribute clamping pressure more evenly
• Prevent unwanted distributor movement
• Support accurate ignition timing
• Prevent the distributor from being mounted too deeply
• Provide a more secure mounting arrangement than the original thin clamp

Why Is This Clamp Recommended for 123Ignition Distributors?

The original Porsche distributor clamp has a clamping surface of only approximately 2mm.

When used with a 123Ignition distributor, this narrow clamping surface can create installation problems. In particular, the original clamp can potentially move into the distributor groove rather than providing the intended support.

This upgraded aluminium version increases the clamping surface to 9mm.

The wider contact area provides better pressure distribution and helps ensure that the distributor rests correctly against the engine housing rather than sitting too low and standing on the drive shaft.

9mm Clamping Surface

One of the main improvements is the substantially wider clamping area.
Original-style clamp: approximately 2mm
Upgraded mounting clamp: 9mm

The increased width provides a more stable contact surface and prevents the clamp from slipping into the distributor groove.

This creates a more positive and secure installation for the 123Ignition distributor.

Correct Distributor Installation Height

A distributor should not be supported by the drive shaft itself.

If a 123Ignition distributor is fitted too deeply into the engine case, it can stand on the distributor drive shaft rather than correctly resting against the engine housing.

This mounting clamp is designed to help establish the correct position, ensuring the distributor is properly supported by the housing while maintaining correct engagement with the drive mechanism.

Alternative to a Spacer Ring

When installing a 123Ignition distributor into a Porsche 356 or 912 3-piece engine case, the use of either a suitable spacer ring or this dedicated mounting clamp is recommended.

This upgraded clamp provides an integrated solution, replacing the original thin clamp and spacer ring arrangement with a single purpose-designed aluminium component.

Porsche 356 / 912 123Ignition Distributor Mounts & Electronic Ignition Upgrades

Upgrading a Porsche 356 or 912 to a 123Ignition electronic distributor is a popular way of introducing modern ignition control while retaining the basic distributor-based layout of the original engine.

Correct installation is essential. The distributor must engage correctly with the drive while sitting at the intended height against the engine housing.

The original thin distributor clamp was designed around the original distributor arrangement and is not necessarily the ideal solution when installing a modern 123Ignition unit.

This purpose-designed aluminium mounting clamp provides a 9mm clamping surface, improving support and pressure distribution while helping maintain the correct distributor position.

It is therefore a worthwhile addition when installing a 123Ignition distributor into a Porsche 356 or 912 3-piece engine case.

The clamping plate forms part of the indicator switch mounting arrangement, allowing the switch assembly to be securely positioned around the steering column. It is an important small component when rebuilding the steering column, replacing an indicator switch or restoring the dashboard and steering controls of a Porsche 356A.

What Does the Indicator Switch Clamping Plate Do?

The clamping plate provides the secure mounting point required to hold the indicator switch assembly in its correct position on the steering column.

When correctly installed, it helps prevent the switch assembly from rotating, moving or becoming loose during operation.

Its main functions include:

• Securing the indicator switch to the steering column
• Maintaining the correct switch position
• Preventing unwanted movement during operation
• Providing a firm mounting point for the indicator switch assembly

Indicator Switch, Steering Column & Electrical Parts

The steering column controls are an important part of both the function and appearance of a classic Porsche 356A interior. Small components such as clamps, mounting plates, switches and associated hardware ensure that the controls remain securely positioned and operate as intended.

During a Porsche 356A restoration, these smaller components can easily be overlooked. However, worn, damaged or missing indicator switch mounting hardware can prevent the switch assembly from fitting securely to the steering column.

Using the correct clamping plate for a 40mm steering column helps restore the original mounting arrangement while providing a secure foundation for the indicator switch.

When rebuilding the assembly, it is also worthwhile inspecting the indicator switch, wiring, steering column components and associated mounting hardware for wear or previous modifications.

Wheel Spacers – 5x205mm Bolt Circle and 160mm Hub Opening
Sold as a pair

Improve wheel clearance, offset or stance while maintaining a discreet, original-style appearance with these OE Match Wheel Spacers for vehicles using the classic 5x205mm bolt pattern.

Fits:

• Porsche 356 1950-55
• Porsche 356A 1955-59
• Porsche 356B 1959-63

The design is particularly suited to original-style wheels. Unlike many conventional wheel spacers that leave a noticeable ring visible behind the rim, these spacers are designed to remain largely hidden once the wheel is installed.

An internal chamfer allows the spacer to sit correctly against the brake drum, providing a clean and precise fit.

What Do Wheel Spacers Do?

Wheel spacers fit between the wheel and the brake drum or hub, moving the wheel further outwards by the thickness of the spacer.

Depending on the application and thickness selected, fitting wheel spacers can:

• Increase wheel-to-suspension clearance
• Adjust the effective wheel offset
• Provide clearance for different wheel and tyre combinations
• Increase vehicle track width
• Position the wheel further towards the edge of the wheel arch
• Create a wider and more purposeful stance

Selecting the correct spacer thickness is important to ensure adequate clearance between the wheel, tyre, suspension and bodywork.

Designed for Original-Style 5x205 Wheels

These spacers have been specifically designed to complement original-style wheels using the traditional 5x205 bolt pattern.

The CNC-machined profile keeps the spacer largely hidden behind the wheel, avoiding the prominent visible ring that can occur with some conventional spacer designs.

This makes them particularly suitable for classic vehicles where improved wheel positioning is required without detracting from the original appearance.

They can also be used with other compatible wheels featuring a 5x205mm bolt pattern, subject to checking the dimensions and clearances of the individual wheel.

Precision Fit Against the Brake Drum

A carefully machined chamfer on the inside of the spacer allows it to locate correctly against the brake drum.

Correct seating is essential when installing wheel spacers. The spacer must sit flat against the mounting surface without interference before the wheel is installed.

Available Spacer Thicknesses

These 5x205 wheel spacers are available in:

• 5mm
• 10mm
• 15mm
• 20mm
• 25mm
• 30mm

The range of thicknesses allows the wheel position to be adjusted according to the individual vehicle, wheel specification and required clearance.

Longer Wheel Bolts May Be Required

Increasing the distance between the wheel and mounting surface reduces the amount of the original wheel bolt that engages with the hub or brake drum.

Longer wheel bolts may therefore be required when fitting these spacers.

As a general rule, the additional wheel bolt length should correspond to the thickness of the spacer being installed. For example, a 15mm spacer will normally require a wheel bolt approximately 15mm longer than the original.

The correct bolt type, length and thread engagement must always be confirmed for the individual vehicle and wheel combination before use.

5x205 Wheel Spacers for Classic Porsche & Wide 5 Wheels

The 5x205 wheel pattern is widely associated with early classic vehicle applications and requires appropriately designed components when altering wheel position or offset.

Wheel spacers provide a straightforward way of moving the wheel outwards without changing the wheel itself. They can be useful when additional inner clearance is required or when owners want to improve the position of the wheel within the bodywork.

For classic vehicles using original-style rims, appearance is also important. These CNC-machined 5x205 wheel spacers are designed to remain discreetly positioned behind the wheel, helping retain a traditional appearance while providing the required increase in track width or clearance.

With thicknesses ranging from 5mm to 30mm, the appropriate spacer can be selected according to the required wheel position and individual vehicle setup.

Wheel Balancing Adaptor for 5x205 Rims – Includes M12x1.5 Fixing Bolts

The adaptor can be used with M12x1.5 or M14x1.5 fixing bolts and is supplied complete with five M12x1.5 bolts.

What Does the Wheel Balancing Adaptor Do?

For a wheel to be balanced correctly, it must be accurately centred and securely mounted on the balancing machine.

Classic 5x205 wheels use a large-diameter five-bolt mounting pattern that may not be compatible with the standard cones and mounting equipment supplied with many modern wheel balancers.

This adaptor provides a dedicated mounting solution for 5x205 rims, allowing the wheel to be attached through its bolt pattern and then mounted to the balancing machine.

This helps provide:

• Accurate mounting of 5x205 wheels
• Secure positioning on modern wheel balancing machines
• Correct wheel centring
• More reliable wheel balancing
• Compatibility with classic wide 5-pattern wheels
• Easier servicing of vehicles using 5x205 rims

Why Is the Correct Balancing Adaptor Important?

Accurate wheel balancing depends on the wheel being correctly centred on the balancing machine.

If a 5x205 wheel is mounted incorrectly or is not perfectly centred, the balancing machine may produce inaccurate readings. This can result in unnecessary wheel weights being fitted or a wheel that still produces vibration once installed on the vehicle.

Using a dedicated 5x205 balancing adaptor allows the wheel to be mounted using its fixing pattern, providing a suitable solution for balancing classic wheels on modern workshop equipment.

How Is the Adaptor Used?

The wheel is secured to the adaptor through its 5x205 mounting holes using suitable fixing bolts.

The adaptor is then clamped onto the balancing machine using its 75mm inner diameter for the clamping sleeve. Once correctly mounted and centred, the wheel can be balanced using the normal operating procedure of the balancing machine.

The adaptor accepts:

• M12x1.5 fixing bolts M14x1.5 fixing bolts
• Five M12x1.5 fixing bolts are included with the adaptor.

Ideal for Classic Porsche and 5x205 Wheel Applications

The 5x205 bolt pattern is commonly associated with classic vehicles and requires specialist equipment when using many modern wheel balancing machines.

This adaptor is particularly useful for classic car specialists, Porsche workshops, restoration businesses and enthusiasts who regularly work with wide 5-pattern wheels.

Having the correct adaptor available eliminates the difficulty of trying to mount these wheels using equipment designed primarily for later wheel designs.

Technical Specifications

• Bolt pattern: 5x205
• Compatible fixing bolts: M12x1.5 and M14x1.5
• Inner diameter for clamping sleeve: 75mm
• Fixing bolts supplied: 5 x M12x1.5

5x205 Wheel Balancing Adaptors & Classic Porsche Workshop Tools

Correct wheel balancing is essential for smooth driving, predictable handling and reducing unnecessary vibration through the steering and suspension.

Classic 5x205 wheels can present a problem for modern tyre shops because many contemporary balancing machines are not equipped with the correct mounting hardware for wide 5-pattern rims.

A dedicated 5x205 wheel balancing adaptor bridges the gap between classic wheel designs and modern workshop equipment. By providing a secure and accurately centred mounting point, the adaptor allows older wheels to be balanced using contemporary balancing machines.

This makes it a useful workshop tool for classic Porsche maintenance, wheel restoration, tyre replacement and complete vehicle restoration projects.

Carburettor Fuel Level Measuring Device – Solex / Zenith with Zenith Injection Quantity Tester

Accurately check and set carburettor fuel levels with this specialist measuring kit for Solex and Zenith carburettors.

Fits:

• Porsche 912 SWB 1965-1968 (F)
• Porsche 356 1950-55
• Porsche 356A 1955-59
• Porsche 356B 1959-63
• Porsche 356C 1963-65

Designed to measure the fuel level while the carburettor is operating, the kit uses a transparent sight glass connected directly to the carburettor. This allows the actual fuel level inside the float chamber to be viewed and compared with the manufacturer's specified setting.

Three rings on the sight glass provide clear visual reference points when checking the fuel level.

The kit also includes a special injector for Zenith NDIX carburettors, allowing the accelerator pump injection quantity to be measured according to the relevant workshop repair procedure.

What Does the Carburettor Level Measuring Kit Do?

Correct fuel level inside the float chamber is essential for accurate carburettor operation.

If the level is too high, excessive fuel can enter the engine, potentially resulting in an overly rich mixture, poor running and increased fuel consumption. If the level is too low, insufficient fuel supply can contribute to hesitation and weak running, particularly when greater fuel delivery is required.

This tool allows the fuel level to be observed directly while the carburettor is operating rather than relying solely on measurements taken with the carburettor dismantled.

The three rings fitted to the sight glass act as convenient visual references for comparing the measured fuel level with the specification given in the appropriate repair guide.

How Is the Kit Used?

Different adaptors supplied with the kit allow the sight glass to be connected to several Solex and Zenith carburettor types.

For Solex 40 PII carburettors, the extended special main nozzle carrier is installed with the main nozzle fitted into the carrier. The sight glass can then be connected so the operating fuel level can be observed.

For Solex PICT carburettors, the supplied banjo bolt and sight glass are fitted to the float chamber.

For Solex PBIC and PICB carburettors, the corresponding extended main nozzle carrier supplied with the kit is used.

For Zenith NDIX carburettors, the sight glass is installed using the long banjo bolt and supplied spacer.

Once connected, the carburettor can be operated and the fuel level viewed through the sight glass. The measured level should then be compared with the specification given in the relevant manufacturer's repair guide.

Zenith NDIX Injection Quantity Measurement

The kit also provides a method of checking the accelerator pump injection quantity on Zenith NDIX carburettors.

The supplied special Zenith injector operates differently from the normal injector. Instead of delivering fuel into the injection pipe, it directs the fuel outwards.

The discharged fuel can then be collected in a suitable graduated glass measuring cylinder and the quantity compared with the specification in the appropriate repair guide.

Please note that the measuring cylinder is not included.

This provides a practical way of checking whether the accelerator pump is delivering the specified quantity of fuel and allows adjustments to be made where required.

Why Is Correct Carburettor Fuel Level Important?

The float chamber must maintain the fuel at the correct height for the carburettor circuits to operate as intended.

Incorrect fuel levels can affect mixture strength and general engine behaviour and may contribute to:

• Rich or lean running
• Poor idle quality
• Hesitation during acceleration
• Difficult starting
• Excessive fuel consumption
• Inconsistent carburettor performance
• Poor response when accelerating

Accurately checking the fuel level is therefore an important part of carburettor setup, troubleshooting and synchronisation.

Ideal for Carburettor Setup and Rebuilding

This kit is particularly useful when rebuilding, setting up or diagnosing classic Solex and Zenith carburettors.

It provides a direct visual method of checking the operating fuel level and, with Zenith NDIX applications, an additional method of measuring accelerator pump injection quantity.

It is suitable for professional workshops, engine builders and experienced enthusiasts carrying out accurate carburettor servicing and adjustment.

Scope of Delivery

• 1 x sight glass with 3 reference rings
• 1 x main nozzle carrier for Solex 40 PII
• 1 x banjo bolt for Solex PICT

• 1 x banjo bolt with adaptor for Zenith NDIX
• 1 x special injector for Zenith NDIX
• 1 x Zenith fibre gasket
• 3 x fibre seals for sight glass/Solex

The correct fuel levels and injection quantities should always be taken from the relevant workshop or repair guide for the specific carburettor and application.

Solex & Zenith Carburettor Setup, Tuning & Measuring Tools

Correct carburettor adjustment is essential for achieving smooth running, reliable starting and good throttle response on classic Porsche and other vehicles equipped with Solex or Zenith carburettors.

Specialist carburettor measuring tools make it possible to diagnose and adjust areas that cannot be accurately assessed through basic external adjustment alone. Checking the float chamber fuel level and accelerator pump delivery can be particularly useful when rebuilding carburettors or investigating poor running, hesitation or inconsistent fuelling.

This Solex and Zenith carburettor level measuring kit supports Solex 40 PII, PICT, PBIC/PICB and Zenith NDIX applications using the dedicated adaptors supplied.

Diagram ref no 31

The improved rigidity of the billet aluminium construction helps maintain an even sealing surface when installed, making it a worthwhile upgrade over an old, distorted or damaged original cover. In addition, 21 integral cooling fins increase the cover's external surface area, helping transfer heat from the engine oil to the surrounding airflow. This provides a useful additional oil-cooling effect while retaining a straightforward bolt-on installation.

Magnet Installation

Please note that a magnet is not included with this cover.

The magnet from the existing oil strainer cover must be transferred to the new billet aluminium cover and secured using the supplied rivet.

This allows the original magnetic function to be retained while benefiting from the upgraded CNC-machined cover.

Finished in black for a discreet appearance, the cover can be installed using the original engine studs, with no longer replacement studs required.

What Does the Oil Strainer Cover Do?

The oil strainer cover is located on the underside of the engine and closes the opening containing the engine oil strainer.

The strainer helps prevent larger particles and contaminants from circulating through the engine lubrication system, while the cover seals the assembly and keeps the engine oil contained.

Because this area is accessed during oil and strainer servicing, the condition and flatness of the cover are particularly important for achieving a reliable seal.

A correctly fitted oil strainer cover helps:

Seal the engine oil strainer opening Prevent oil leakage Secure the oil strainer assembly Provide access during oil system servicing Maintain the integrity of the lubrication system

What Do the 21 Cooling Fins Do?

This upgraded version incorporates 21 cooling fins directly into the aluminium cover.

The fins increase the surface area exposed to airflow underneath the vehicle. As heat passes from the engine oil into the aluminium cover, the increased surface area helps dissipate some of this heat into the surrounding air.

The fins therefore provide supplementary oil cooling without requiring an additional external oil cooler or major modifications to the engine.

This can be particularly useful on engines exposed to sustained higher temperatures during enthusiastic road driving or other demanding operating conditions.

Why Do Original Oil Strainer Covers Fail?

Original-style covers can deteriorate or become distorted after decades of use and repeated servicing.

One of the most common problems is deformation around the mounting holes caused by repeated tightening or previous over-tightening. Once the cover is no longer completely flat, the gasket may not be compressed evenly against the engine case.

Common problems include:

• Warping or distortion
• Deformation around mounting holes
• Over-tightened mounting hardware
• Damaged sealing surfaces
• Scratches and corrosion
• Repeated removal and installation
• General age-related deterioration

A distorted cover can contribute to oil seepage even when new gaskets are fitted.

Why Upgrade to a Billet Aluminium Version?

The major advantage of this upgraded cover is its rigid CNC-machined aluminium construction.

Machining the component provides a precise, flat sealing surface, helping the gasket sit evenly between the cover and engine case. The increased rigidity also makes the cover less prone to the distortion commonly found on older conventional drain plates.

Benefits include:

• CNC-machined aluminium construction
• Perfectly flat contact surface Increased rigidity
• Reduced tendency to distort
• Improved support for the sealing gasket 21 integrated cooling fins
• Additional oil heat dissipation
• Durable replacement for an ageing original cover
• Black finish
• Straightforward installation using original studs

For Porsche 356 and 912 engines suffering from a distorted original cover, or where improved oil cooling is desirable, the billet finned version combines improved sealing characteristics with an additional cooling function.

Easy Installation

The cover has been designed to fit using the original engine case studs.

No longer studs are required, helping maintain the original mounting arrangement and making this a straightforward upgrade during routine oil system servicing or an engine rebuild.

Finned Oil Strainer Covers & Engine Oil Cooling Upgrades

Maintaining effective lubrication and controlling engine oil temperature are important considerations for classic Porsche 356 and 912 engines.

Original oil strainer covers can become distorted after years of servicing, potentially making it difficult for the gasket to seal correctly. Replacing a warped cover with a CNC-machined billet aluminium version provides a flatter and more rigid sealing surface while retaining straightforward access to the oil strainer.

The addition of 21 cooling fins provides another useful advantage. By increasing the surface area of the aluminium cover exposed to airflow beneath the vehicle, additional heat can be dissipated from the oil system.

This makes the finned billet cover a practical upgrade for owners looking to combine improved sealing, increased component rigidity and supplementary oil cooling in a single direct-fit component.

When replacing the oil strainer cover, it is also worthwhile inspecting the oil strainer, gaskets, magnet, mounting hardware and engine case sealing surface before reassembly.

What Does the Oil Strainer Cover Do?

The oil strainer cover is fitted to the underside of the engine and closes the opening for the engine oil strainer.

The strainer itself helps prevent larger particles and contaminants from circulating through the engine lubrication system, while the cover provides the sealing surface required to contain the engine oil.

Because the cover is removed during servicing and oil strainer maintenance, maintaining a flat and correctly sealed surface is particularly important.

A correctly fitted oil strainer cover helps:

• Seal the engine oil strainer opening
• Prevent engine oil leaks
• Secure the oil strainer assembly
• Provide access during oil system servicing
• Maintain the integrity of the engine lubrication system

Why Do Original Oil Strainer Covers Fail?

Original-style covers can become distorted after years of use and repeated removal and installation.

One of the most common problems is deformation around the mounting holes caused by repeated tightening of the retaining nuts. Once the plate is no longer completely flat, the gasket may struggle to seal evenly against the engine case.

Other causes of deterioration can include:

• Repeated tightening and removal
• Over-tightening of mounting hardware
• Distortion around the stud holes
• Damage to the sealing surface
• Corrosion and general age
• Scratches or previous incorrect installation

A distorted cover can contribute to the familiar oil seepage sometimes found around the bottom of older Porsche 356 and 912 engines.

Why Upgrade to Billet Aluminium?

The main advantage of this upgraded cover is its CNC-machined billet aluminium construction.

Rather than relying on a thinner plate that can become distorted over time, the billet design provides a rigid and accurately machined sealing surface.

Benefits include:

• CNC machined from aluminium
• Perfectly flat contact surface
• Increased rigidity
• Reduced tendency to distort
• Improved support for the sealing gasket
• Durable replacement for an ageing original cover
• Black finish for a discreet appearance
• Reuses the original mounting studs

For engines that are regularly serviced or have experienced persistent seepage around the strainer cover, upgrading to a rigid billet version can provide a more dependable foundation for achieving a good seal.

Installation

The 53901150 cover has been designed to fit using the original engine case studs.

There is no requirement to replace the standard studs with longer versions, simplifying installation and maintaining the original mounting arrangement.

Oil Strainer Covers, Drain Plates & Engine Lubrication Parts

Oil leaks around the lower engine area are a common concern when maintaining older Porsche 356 and 912 engines. While replacing gaskets is often the first step, a gasket cannot always compensate for a cover that has become warped or distorted.

A CNC-machined billet aluminium oil strainer cover provides a rigid, accurately machined sealing surface and is therefore a useful upgrade during an engine rebuild, restoration or routine oil system refurbishment.

When replacing the oil strainer cover, it is also worthwhile inspecting the strainer, gaskets, mounting hardware and surrounding sealing surfaces. Correct installation and tightening are important to avoid damaging components and to achieve an effective seal.

The particulate matter sensor monitors particulate content in the exhaust gas and communicates relevant information to the vehicle's electronic control system.

Its role is primarily related to emissions monitoring and diagnostics. Depending on the specific vehicle and exhaust configuration, the sensor allows the control system to evaluate whether the associated exhaust aftertreatment and particulate filtration system is operating within its expected parameters.

A correctly functioning particulate matter sensor helps:

• Monitor particulate levels in the exhaust
• Support emissions-system diagnostics
• Monitor exhaust aftertreatment performance
• Help detect abnormal particulate emissions
• Provide accurate information to the vehicle's control electronics
• Support onboard diagnostic functions
• Help ensure correct operation of emissions-related systems

Common signs of sensor failure can include:

• Check Engine Light / engine-management warning
• Emissions-system warning messages
• Stored particulate sensor fault codes
• Exhaust aftertreatment-related diagnostic codes
• Implausible or inconsistent sensor readings
• No sensor signal during diagnostic testing
• Failed sensor self-diagnostics
• Intermittent emissions warnings
• Failed emissions or inspection testing
• Damaged sensor wiring
• Heat-damaged electrical connections
• Corroded or damaged connectors

In some cases there may be little or no noticeable difference in normal driving behaviour, with the fault primarily appearing as a warning light or diagnostic code.

Why Replacement Matters:
A failed particulate matter sensor can prevent the vehicle's control system from accurately monitoring exhaust emissions and the operation of associated aftertreatment equipment.

Replacing a confirmed defective sensor helps restore:

• Accurate particulate monitoring
• Correct emissions-system feedback
• Reliable onboard diagnostics
• Proper exhaust aftertreatment monitoring
• Accurate identification of emissions faults
• Reduced likelihood of recurring sensor-related warning messages
• Correct communication between the exhaust sensor and vehicle electronics

Leaving a failed sensor in place may result in persistent warning lights and can make it more difficult to identify faults elsewhere in the emissions system.
