On turbocharged engines, accurate boost pressure data is essential for controlling performance and protecting the engine. The ECU uses the sensor signal to compare actual boost pressure against the pressure required for the current engine speed, load and throttle demand.

A correctly functioning boost pressure sensor helps the engine-management system maintain consistent turbocharger performance, efficient combustion and predictable power delivery. If the sensor becomes contaminated, electrically faulty or inaccurate, the ECU may receive incorrect pressure information, potentially resulting in reduced performance, inconsistent boost or a protective reduced-power mode.

This OE Match Boost Pressure Sensor provides a high-quality replacement for a contaminated, damaged or failed original sensor, helping restore accurate boost pressure feedback and reliable turbocharged engine operation.

What This Product Does:

• Measures pressure within the applicable intake or boost system.
• Sends boost pressure information to the ECU.
• Allows the ECU to monitor actual turbocharger boost pressure.
• Helps the engine-management system compare requested and actual boost.
• Supports correct turbocharger control.
• Helps maintain consistent power delivery.
• Supports accurate engine load calculations.
• Helps maintain responsive acceleration and throttle operation.
• Assists the ECU in detecting underboost conditions.
• Assists the ECU in detecting overboost conditions.
• Supports engine and turbocharger protection strategies.
• Provides important data for engine-management diagnostics.
• Replaces an inaccurate, contaminated or failed pressure sensor.
• Provides an OE Match alternative for compatible Porsche applications.  

Symptoms Of Wear Or Failure:

• Check engine or engine-management warning light.
• Boost pressure-related diagnostic trouble codes.

• Sluggish throttle response.
• Inconsistent turbocharger boost.
• Sudden loss of boost.
• Engine entering a reduced-power or protective mode.
• Hesitation under acceleration.
• Uneven or unpredictable power delivery.
• Increased fuel consumption.
• Engine performance that changes intermittently.
• Implausible boost pressure readings during diagnostic testing.
• Pressure readings that do not correspond with engine load.
• Damaged electrical wiring or connector.
• Contamination around the sensor or sensing element.  

Why Replacement Matters:

• Accurate boost pressure information is critical to the control of a turbocharged engine. The ECU relies on the sensor to determine whether the turbocharging system is producing the expected pressure.
• If the sensor reports an inaccurate value, the ECU may interpret a correctly operating turbocharger as producing too much or too little boost. This can trigger diagnostic faults and cause the engine-management system to limit power as a protective measure.
• A sensor that reads incorrectly can therefore cause significant performance problems even when the turbocharger itself is mechanically sound.
• Accurate boost monitoring is also important for engine protection. Excessive boost can increase cylinder pressures, combustion temperatures and mechanical loads, while insufficient boost can indicate leaks or problems elsewhere in the turbocharging system.
• An intermittent sensor can be particularly troublesome because the vehicle may perform normally during some journeys and unexpectedly lose power during others.
• Replacing a defective component with this OE Match Boost Pressure Sensor helps restore accurate pressure feedback, consistent boost control and dependable engine-management operation.

Maintaining the correct engine oil level is essential for lubrication, cooling and protection of internal engine components. The oil level sender allows the vehicle to provide the driver with an indication of oil level and, where applicable, a warning when the quantity falls outside the expected range.

Over time, an oil level sender can deteriorate through repeated heat cycles, vibration, oil contamination, electrical faults or damage to its wiring and connector. A defective sender may produce inaccurate or intermittent readings, trigger warning messages despite the oil being correctly filled, or fail to identify a genuine low-oil condition.

This OE Match Oil Level Sender provides a high-quality replacement for a faulty or damaged original sender, helping restore dependable electronic oil level monitoring.

What This Product Does:

• Monitors the engine oil level.
• Provides oil level information to the vehicle's electronic system.
• Supports the dashboard or instrument oil level display where applicable.
• Helps identify when engine oil quantity is too low.
• Supports accurate monitoring between routine manual oil checks.

Symptoms Of Wear Or Failure:

• Incorrect engine oil level displayed.
• Low oil warning despite the engine having the correct oil quantity.
• Oil level display showing full when the level is actually low.
• Oil level reading stuck at one value.
• Intermittent or fluctuating oil level readings.
• Oil level measurement unavailable on the instrument display.
• Implausible oil level readings.
• Engine oil level sensor-related warning messages.
• Relevant diagnostic fault codes.
• Warning returning shortly after the oil level has been correctly adjusted.
• Damaged sender wiring or electrical connector.
• Oil contamination or deterioration around the sender connection.
• Physical damage discovered during engine servicing.  

Why Replacement Matters:

• Correct engine oil quantity is critical to engine reliability. Engine oil lubricates bearings, camshafts and numerous other moving components while also contributing to heat management and internal cleanliness.
• A faulty oil level sender can create two distinct problems. If it reports a falsely low level, the driver may unnecessarily add oil. Overfilling an engine can itself cause problems, including oil aeration, increased crankcase pressure and potential contamination of intake or emissions systems depending on the engine design.
• More importantly, a sender that incorrectly reports an adequate level may prevent the driver from recognising genuine oil loss or consumption.
• Operating an engine with insufficient oil can reduce lubrication and increase component temperatures. In severe cases, low oil quantity can contribute to accelerated wear or major internal engine damage.
• It is also important to distinguish oil level from oil pressure. This sender monitors oil quantity; it does not replace the engine's oil pressure monitoring system. An oil pressure warning should be treated as a separate and potentially urgent issue.
• Replacing a defective component with this OE Match Oil Level Sender helps restore trustworthy oil level information and allows the driver to maintain the correct engine oil quantity with greater confidence.

• Corroded or contaminated electrical connections.
• Damaged sensor wiring.
• Cracked or damaged electrical connector.
• Physical deterioration of the sensor.
• Sensor problems discovered during expansion tank servicing or replacement.  

Why Replacement Matters:

• The coolant level sensor provides an important warning when the cooling system begins losing coolant. A faulty sensor can create problems in two different ways.
• If the sensor incorrectly reports a low level, it may produce persistent or intermittent dashboard warnings even when the cooling system is correctly filled.
• More importantly, a sensor that fails to detect an actual low coolant condition can prevent the driver from receiving an early warning.
• Coolant loss may result from a leaking hose, radiator, expansion tank, water pump, seal or another cooling-system component. Continuing to drive with insufficient coolant can lead to poor circulation, air entering the cooling circuit and eventual engine overheating.
• Severe overheating can cause expensive engine damage, including deterioration of seals and gaskets and damage to major engine components.

RIGHT Lambda Oxygen Sensor, BEFORE Catalytic Converter.

Restore accurate fuel-mixture monitoring and dependable engine-management performance with this OE Match Right Lambda Oxygen Sensor. Designed for compatible Porsche applications, this sensor is specified for the RIGHT side, BEFORE the catalytic converter.

Fits: 

• Porsche 958 Cayenne V6 3.6L Petrol (300Hp) 2010-17  

Diagram Ref No 18

Also known as an upstream, pre-cat or O2 sensor, the lambda sensor measures the oxygen content remaining in the exhaust gases after combustion. This information is sent to the engine control unit (ECU), allowing it to determine whether the engine is operating with a rich or lean air-fuel mixture and make precise adjustments to fuel delivery.

Because this sensor operates before the catalytic converter, it plays an important role in closed-loop fuel control. Accurate readings help maintain efficient combustion, responsive engine performance, appropriate fuel consumption and controlled exhaust emissions.

Lambda sensors operate in a particularly demanding environment, exposed to extreme exhaust temperatures, vibration and combustion deposits. Over time, the sensing element can become contaminated or slow to respond, while the heater circuit, wiring or electrical connector can also deteriorate.

This OE Match Right Lambda Oxygen Sensor provides a high-quality replacement for a worn, contaminated, damaged or failed original sensor.

What This Product Does:

• Is designed for the RIGHT-side application.
• Is positioned BEFORE the catalytic converter.
• Measures oxygen content in the exhaust gases.
• Sends exhaust oxygen information to the ECU.
• Helps determine whether the air-fuel mixture is rich or lean.
• Allows the ECU to make continuous fuel-delivery corrections.
• Supports accurate closed-loop mixture control.
• Helps maintain efficient combustion.
• Supports smooth throttle response and engine performance.
• Helps optimise fuel consumption.
• Contributes to correct exhaust emissions.
• Helps protect the catalytic converter from problems associated with incorrect fuelling.
• Replaces a slow, contaminated, damaged or failed lambda sensor.
• Provides an OE Match alternative for compatible Porsche applications.  

Symptoms Of Wear Or Failure:

• Check engine or engine-management warning light.
• Lambda or oxygen sensor-related diagnostic fault codes.
• Bank-specific rich or lean mixture fault codes.
• Increased fuel consumption.
• Rough or unstable idle.
• Hesitation during acceleration.
• Poor throttle response.
• Reduced engine performance.
• Engine running excessively rich or lean.
• Strong fuel smell from the exhaust.
• Increased exhaust emissions.
• Failed emissions testing where applicable.
• Intermittent engine-management warnings.
• Slow sensor response during diagnostic testing.
• Implausible or inconsistent lambda readings.
• Oxygen sensor heater circuit faults.
• Damaged wiring, insulation or electrical connectors.  

Why Replacement Matters:

• The pre-catalytic converter lambda sensor provides essential feedback for controlling the engine's air-fuel mixture. The ECU relies on this information to make continual fuel-delivery adjustments as engine speed, load and operating conditions change.
• As a lambda sensor ages, its response may become progressively slower or less accurate without immediately failing completely. This can result in less precise mixture control and contribute to increased fuel consumption, reduced performance, unstable running and higher emissions.
• Incorrect fuelling can also affect the catalytic converter. An excessively rich mixture may allow unburned fuel to enter the exhaust system, increasing catalyst temperatures and potentially shortening catalytic converter life.
• A completely failed sensor may cause the ECU to substitute calculated values or adopt a fallback operating strategy. The engine may remain driveable, but efficiency, emissions and performance can be compromised.
• Because it is specified for the right-side, pre-catalytic converter position, correct sensor location is particularly important on engines equipped with multiple exhaust banks and lambda sensors.
• Replacing a defective sensor with this OE Match Right Lambda Oxygen Sensor helps restore accurate mixture feedback, efficient combustion and dependable engine-management performance.

Diagram Ref No 7

Also known as an upstream, pre-cat or O2 sensor, the lambda sensor provides essential feedback to the engine control unit (ECU). By measuring residual oxygen in the exhaust stream, it enables the ECU to determine whether the engine is operating with a rich or lean air-fuel mixture and make continuous corrections to fuel delivery.

As a pre-catalytic converter sensor, it has an important role in closed-loop fuel control. Accurate readings help maintain efficient combustion, responsive performance, appropriate fuel consumption and controlled exhaust emissions.

Lambda sensors operate under demanding conditions and are continually exposed to extreme exhaust temperatures, vibration and combustion deposits. With age, the sensing element can become contaminated or slow to respond, while the internal heater, wiring or electrical connections may also deteriorate.

This OE Match Lambda Oxygen Sensor provides a high-quality replacement for a slow, contaminated, damaged or failed original sensor.

What This Product Does:

• Measures oxygen content within the exhaust gases.
• Is designed for installation before the catalytic converter.
• Sends exhaust oxygen information to the ECU.
• Helps determine whether the engine is running rich or lean.
• Allows the ECU to make accurate fuel-delivery adjustments.
• Supports closed-loop air-fuel mixture control.
• Helps maintain efficient combustion.
• Contributes to smooth and responsive engine performance.
• Helps optimise fuel consumption.
• Supports correct exhaust emissions.
• Helps protect the catalytic converter from problems caused by incorrect fuelling.
• Replaces a worn, contaminated or failed oxygen sensor.
• Provides an OE Match alternative for compatible Porsche applications.  

Symptoms Of Wear Or Failure:

• Check engine or engine-management warning light.
• Lambda or oxygen sensor-related diagnostic fault codes.
• Rich or lean mixture fault codes.
• Increased fuel consumption.
• Rough or unstable idle.
• Hesitation during acceleration.
• Poor throttle response.
• Reduced engine performance.
• Engine running excessively rich or lean.
• Strong fuel smell from the exhaust.
• Increased exhaust emissions.
• Failed emissions testing where applicable.
• Intermittent engine-management warnings.
• Slow sensor response shown by diagnostic equipment.
• Implausible or inconsistent lambda readings.
• Oxygen sensor heater circuit faults.
• Damaged wiring, insulation or electrical connectors.  

Why Replacement Matters:

• The lambda sensor positioned before the catalytic converter is a key feedback component within the engine-management system. The ECU relies on its signal to continually fine-tune the amount of fuel delivered to the engine.
• As a lambda sensor ages, it may become slower to react to changes in exhaust oxygen content. A sensor does not necessarily have to fail completely to affect engine operation; delayed or inaccurate readings can result in less precise fuel corrections.
• Poor mixture control can contribute to increased fuel consumption, reduced performance, unstable running and higher exhaust emissions.
• Incorrect fuelling can also place additional stress on the catalytic converter. If the engine runs excessively rich, unburned fuel can enter the exhaust system and increase catalyst temperatures, potentially shortening catalytic converter service life.
• A failed sensor may cause the ECU to use substitute values or adopt a fallback strategy. Although the engine may continue to run, fuel efficiency, emissions and performance may be compromised.
• Replacing a defective sensor with this OE Match Lambda Oxygen Sensor helps restore accurate mixture feedback, efficient combustion and dependable engine-management operation.

Lambda Oxygen Sensor, BEFORE Catalytic Converter.

Restore accurate air-fuel mixture monitoring and efficient engine-management operation with this OE Match Lambda Oxygen Sensor. Designed for compatible Porsche applications, this sensor is installed before the catalytic converter, where it monitors oxygen levels in the exhaust gases directly after combustion.

Fits:

• Porsche 955 Cayenne Turbo 4.5L 2003-06

Diagram Ref No 6

Also known as an upstream, pre-cat or O2 sensor, the lambda sensor provides essential feedback to the engine control unit (ECU). By measuring the amount of oxygen remaining in the exhaust, the sensor enables the ECU to determine whether the engine is operating with a rich or lean air-fuel mixture and make the necessary fuel-delivery corrections.

Because this sensor operates upstream of the catalytic converter, it plays a particularly important role in closed-loop fuel control. Accurate readings contribute to efficient combustion, responsive engine performance, fuel economy and emissions control.

Continuous exposure to high exhaust temperatures, vibration and combustion deposits can cause lambda sensors to deteriorate over time. A worn sensor may become slow to respond, provide inaccurate readings or fail completely.

This OE Match Lambda Oxygen Sensor provides a high-quality replacement for a worn, contaminated or defective pre-catalytic converter sensor.

What This Product Does:

• Measures oxygen content within the exhaust gases.
• Is designed for installation before the catalytic converter.
• Sends exhaust oxygen information to the ECU.
• Helps determine whether the air-fuel mixture is rich or lean.
• Allows the ECU to continuously adjust fuel delivery.
• Supports accurate closed-loop fuel control.
• Helps maintain efficient combustion.
• Contributes to consistent throttle response and engine performance.
• Helps optimise fuel consumption.
• Supports correct exhaust emissions.
• Helps protect the catalytic converter from problems caused by incorrect fuelling.
• Replaces a slow, contaminated, damaged or failed oxygen sensor.
• Provides an OE Match replacement for compatible Porsche applications.  

Symptoms Of Wear Or Failure:

• Check engine or engine-management warning light.
• Lambda or oxygen sensor-related diagnostic fault codes.

• Failed emissions testing where applicable.
• Intermittent engine-management faults.
• Slow sensor response visible through diagnostic equipment.
• Implausible or inconsistent oxygen sensor readings.
• Sensor heater circuit faults where applicable.
• Damaged wiring or electrical connectors.  

Why Replacement Matters:

• The pre-catalytic converter lambda sensor is one of the engine-management system's primary tools for controlling the air-fuel mixture.
• When operating correctly, the sensor provides rapid feedback that allows the ECU to continually adjust fuel delivery according to actual combustion conditions. If the sensor becomes slow or inaccurate, these adjustments may no longer be as precise.
• Poor mixture control can result in increased fuel consumption, reduced performance and higher emissions. In some cases, the engine may continue to operate relatively normally while efficiency gradually deteriorates.
• Incorrect fuelling can also place the catalytic converter at risk. An excessively rich mixture may allow unburned fuel to enter the exhaust system, increasing catalyst temperatures and potentially contributing to premature catalytic converter damage.
• A completely failed sensor may cause the ECU to use substitute values or a more conservative operating strategy, potentially illuminating the engine-management warning light and reducing overall efficiency.
• Replacing a defective sensor with this OE Match Lambda Oxygen Sensor helps restore accurate mixture feedback, efficient combustion and dependable engine-management operation.

Lambda Oxygen Sensor, BEFORE Catalytic Converter.
Restore accurate air-fuel mixture monitoring and dependable engine-management operation with this OE Match Lambda Oxygen Sensor. Designed for compatible Porsche applications, this sensor is installed before the catalytic converter, where it measures the oxygen content of the exhaust gases leaving the engine.  
 
Fits:

Diagram Ref No 6

Also known as an upstream, pre-cat or O2 sensor, the lambda sensor provides critical feedback to the engine control unit (ECU). By monitoring residual oxygen in the exhaust stream, it allows the ECU to determine whether the engine is running richer or leaner than intended and make continuous adjustments to fuel delivery.

Accurate pre-catalyst lambda sensor information is important for maintaining efficient combustion, responsive performance, fuel economy and emissions control. Unlike a downstream sensor, which is commonly used to monitor catalytic converter performance, the before-catalytic-converter sensor has a direct role in fuel-mixture regulation.

Lambda sensors operate in an extremely demanding environment and are continually exposed to high exhaust temperatures and combustion by-products. Age, contamination, wiring damage or deterioration of the sensing element can eventually cause slow, inaccurate or failed readings.

This OE Match Lambda Oxygen Sensor provides a high-quality replacement for a worn or defective pre-cat sensor, helping restore accurate mixture feedback and correct engine-management operation.

What This Product Does:

• Measures oxygen content in the exhaust gases.
• Is positioned before the catalytic converter.
• Provides air-fuel mixture feedback to the ECU.
• Helps the ECU determine whether combustion is rich or lean.
• Allows continuous adjustment of fuel delivery.
• Supports accurate closed-loop fuel control.
• Helps maintain efficient combustion.

• Failed emissions testing where applicable.
• Intermittent engine-management faults.
• Slow or implausible lambda sensor readings during diagnostic testing.
• Damaged sensor wiring or electrical connector.
• Heater circuit-related sensor faults where applicable.  

Why Replacement Matters:

• The pre-catalytic converter lambda sensor is a key feedback device for the engine's fuel-management system. When operating correctly, it allows the ECU to continually fine-tune the air-fuel mixture as driving conditions change.
• As a lambda sensor ages, its response can become slower even before it fails completely. Delayed or inaccurate feedback may cause the ECU to make less precise fuelling corrections, potentially resulting in increased fuel consumption, reduced performance and higher emissions.
• Incorrect fuelling can also affect the catalytic converter. An excessively rich mixture may allow unburned fuel to enter the exhaust, potentially causing the catalyst to operate at abnormally high temperatures. Persistent lean-running conditions can also contribute to poor engine operation and increased combustion temperatures.
• A failed sensor may cause the ECU to rely on substitute values or an alternative control strategy. While the vehicle may continue to operate, performance, efficiency and emissions can be compromised.
• Replacing a defective component with this OE Match Pre-Catalytic Converter Lambda Oxygen Sensor helps restore accurate mixture feedback, efficient combustion and dependable engine-management operation.

The exterior temperature sensor is positioned where it can monitor outside air temperature while minimising the influence of heat generated by the engine and other vehicle components. Its readings can be used to provide the driver with an outside temperature indication and, depending on the vehicle specification, may also be referenced by other temperature-dependent systems.

Over time, exposure to water, road dirt, temperature extremes and vibration can cause the sensor or its electrical connections to deteriorate. A faulty sensor may display an incorrect outside temperature, produce intermittent readings or stop providing temperature information altogether.

This OE Match Exterior Temperature Sensor provides a high-quality replacement for a failed, damaged or inaccurate original sensor, helping restore dependable ambient temperature measurement.
What This Product Does:

• Measures ambient temperature outside the vehicle.
• Converts outside temperature into an electrical signal.
• Provides temperature information to the relevant vehicle system
• Supports accurate outside temperature display where fitted.
• Helps the driver monitor changing external conditions.

• Sensor-related diagnostic fault codes.
• Visible damage to the sensor.
• Corroded or contaminated electrical connections.
• Broken or damaged sensor wiring.
• Physical damage caused by road debris or previous repairs.  

Why Replacement Matters:

• An exterior temperature sensor provides useful information about the conditions surrounding the vehicle. An inaccurate sensor can make the displayed temperature misleading and reduce the driver's ability to recognise potentially cold or changing road conditions.
• Where the vehicle provides a low-temperature or frost warning, an incorrect sensor reading may cause the warning to appear at the wrong time or prevent it from operating as expected.
• Depending on vehicle specification, ambient temperature information may also be referenced by other electronic systems. An implausible sensor signal can therefore potentially affect functions beyond the temperature display itself.
• Sensor problems are often caused by age, corrosion or physical damage. Because the sensor is exposed to external conditions, its wiring and connector can also deteriorate over time.
• Replacing a defective component with this OE Match Exterior Temperature Sensor helps restore accurate ambient temperature information and dependable operation of systems that use the exterior temperature signal.

Crankshaft Position Sensor, Cylinder 6-10.

Restore accurate engine speed and crankshaft position monitoring with this OE Match Crankshaft Position Sensor, specified for the cylinders 6–10 application on compatible Porsche engines.

Fits:

Diagram Ref No 40

The crankshaft position sensor is a critical engine-management component. It monitors the rotational position and speed of the crankshaft and sends this information to the engine control unit (ECU). The ECU uses this signal to coordinate essential functions such as ignition timing and fuel injection.

Accurate crankshaft position information allows the engine management system to determine precisely where the engine is within its operating cycle. If the sensor signal becomes weak, intermittent or disappears completely, the ECU may be unable to control ignition and injection correctly. This can lead to difficult starting, misfires, poor running or a complete no-start condition.

Electrical sensors can deteriorate through age, repeated heat cycles, vibration, damaged wiring or connector problems. Some failures can also be temperature-related, with the sensor working correctly when cold but becoming unreliable once the engine reaches operating temperature.

This OE Match Crankshaft Position Sensor provides a high-quality replacement for a faulty or damaged sensor, helping restore accurate engine timing information and dependable engine-management operation.

What This Product Does:

• Monitors crankshaft rotational position.
• Measures crankshaft speed or engine RPM.

• Crankshaft position sensor-related diagnostic fault codes.
• Engine speed signal disappearing during diagnostic testing.
• Tachometer or RPM information behaving abnormally where applicable.
• Damaged sensor wiring or electrical connector.
• Heat-related intermittent sensor failure.  

Why Replacement Matters:

• A sensor that fails completely can potentially prevent the engine from starting. An intermittent sensor can be more difficult to diagnose because the vehicle may operate normally before suddenly stalling or refusing to restart.
• Heat-related deterioration is particularly troublesome. A failing sensor may work when the engine is cold but lose its signal as temperatures rise, potentially causing the engine to cut out during operation.
• An inaccurate or unstable signal can also contribute to misfires, poor performance and engine-management warning lights.
• Because crankshaft position information is directly related to ignition and injection control, unresolved sensor faults can compromise overall engine reliability and may leave the vehicle unable to start.
• Replacing a defective component with this OE Match Crankshaft Position Sensor helps restore accurate engine speed and position information, dependable starting and correct engine-management operation.
