Gas Temperature Sensors

Exhaust Gas Temperature Sensor. 

The OE MATCH Exhaust Gas Temperature Sensor is a engine management and emissions control component designed to accurately monitor exhaust gas temperatures on compatible Porsche models. This precision sensor continuously measures the temperature of the exhaust gases and transmits real-time data to the engine control unit (ECU), allowing the engine and emissions systems to operate efficiently while protecting critical components from excessive heat.  

Fits:

• Porsche 958 Cayenne V6 3.0L Diesel (245Hp) 2010-17
• Porsche 970.2 Panamera Diesel V6 3.0L (250Hp) 2014-16
• Porsche 95B.1 Macan S Diesel 3.0L V6 (258Bhp) 2014-18

Diagram Ref No 5 

The sensor is engineered to withstand extreme exhaust temperatures, vibration, thermal cycling and harsh operating conditions. Designed as a replacement, it provides correct fitment and seamless integration with the vehicle's engine management, turbocharging and emissions control systems.  

What This Product Does:

• Monitors exhaust gas temperature.
• Sends accurate temperature data to the engine control unit (ECU).
• Helps protect the turbocharger and exhaust components from excessive heat.
• Supports efficient engine management and fuel control.
• Assists the operation of emissions control systems.
• Optimises engine performance and fuel efficiency.
• Forms an essential part of the exhaust and emissions monitoring system.

Symptoms Of Wear Or Failure:

• Illuminated engine management or check engine warning light.
• Exhaust gas temperature sensor fault codes.
• Reduced engine performance.
• Vehicle entering limp-home mode.
• Increased fuel consumption.
• Poor turbocharger performance.
• Incorrect exhaust temperature readings.
• Reduced efficiency of the emissions control system.
• Failed emissions or MOT inspection.
• Intermittent engine management faults.

Why Replacement Matters:

• The exhaust gas temperature sensor operates in one of the harshest environments on the vehicle, where it is continually exposed to extremely high exhaust temperatures, vibration and rapid thermal cycling. Over time, the sensing element can degrade or become contaminated, while the wiring and connectors may suffer from heat-related deterioration.
• A faulty sensor can provide inaccurate temperature readings to the ECU, causing incorrect engine management strategies, increased emissions and reduced engine performance. In turbocharged applications, incorrect exhaust temperature monitoring may also reduce the system's ability to protect the turbocharger and exhaust after-treatment components from excessive heat.

Gas temperature sensor.
Ensure precise exhaust temperature monitoring in your Porsche with this OE Match gas temperature sensor (95860668831). Designed as a direct replacement for the factory unit, this sensor accurately measures exhaust gas temperature (EGT) and transmits data to the engine control unit (ECU) to maintain optimal performance, emissions control, and turbocharger protection.

Fits:
Porsche 958 Cayenne Diesel 3.0L 2011-15 (Engine Type: CRCA)
Porsche 970 Panamera Diesel 3.0L 2012-16 (Engine Type: CRCC / CRCB)
Porsche 95B Macan Diesel 3.0L - 2014-18 (Engine Type: CDUD)

Diagram ref no 5

Function
The gas temperature sensor (EGT sensor) measures the exhaust gas temperature before or after the turbocharger and transmits the signal to the ECU. The ECU uses this data to adjust fuel injection, ignition timing, and turbo boost, ensuring safe operating temperatures, optimal efficiency, and emissions compliance.

Why replacement matters:
Continuous exposure to high exhaust temperatures and vibration can cause the gas temperature sensor or its wiring to deteriorate over time. This leads to inaccurate readings, erratic ECU data, or the appearance of fault codes that affect performance and emissions control.

When to Replace:
• When a check engine light
• During turbocharger, DPF, or exhaust system replacement or servicing
• As part of preventive maintenance on high-mileage vehicles to maintain precise exhaust temperature management.

Installing a new gas temperature sensor ensures accurate readings, optimal ECU operation, and reliable protection for the engine and turbocharger against overheating or inefficiency.

Temperature Sensor Exhaust Gas.
The OE Match Exhaust Gas Temperature Sensor is a premium-quality replacement engine management and emissions control component designed to accurately monitor exhaust gas temperatures on compatible Porsche models. Manufactured to OE specifications for fit, accuracy and durability, this precision sensor continuously measures exhaust gas temperatures and transmits real-time data to the engine control unit (ECU), enabling optimum engine performance, turbocharger protection and efficient emissions control.  

Fits:

Diagram Ref No 33

Manufactured with a high-temperature-resistant sensing element, stainless steel probe and heat-resistant wiring harness, the sensor is engineered to withstand extreme exhaust temperatures, vibration, moisture and repeated thermal cycling. Designed for direct OE-style installation, it integrates seamlessly with the original engine management and exhaust after-treatment systems, restoring accurate temperature monitoring and reliable system operation.  

What This Product Does:

• Monitors exhaust gas temperature.
• Sends accurate temperature data to the engine control unit (ECU).
• Helps protect the turbocharger and exhaust components from excessive heat.
• Supports efficient engine management and fuel delivery.
• Assists the operation of the emissions control system.
• Supports diesel particulate filter (DPF) regeneration where applicable.
• Restores factory exhaust temperature monitoring.
• Forms an essential part of the engine management and exhaust system.

Symptoms Of Wear Or Failure:

• Illuminated engine management or check engine warning light.
• Exhaust temperature sensor fault codes.
• Reduced engine performance.
• Vehicle entering limp-home mode.
• Increased fuel consumption.
• Failed or interrupted DPF regeneration on diesel models.
• Reduced turbocharger performance.
• Increased exhaust emissions.
• Failed emissions or MOT inspection.
• Intermittent engine management faults.

Why Replacement Matters:

• The exhaust gas temperature sensor operates in one of the harshest environments on the vehicle, where it is continually exposed to extreme temperatures, vibration and rapid heating and cooling cycles. Over time, the sensing element can deteriorate or become contaminated, while prolonged heat exposure may affect the wiring or electrical connections.
• A faulty sensor can provide inaccurate temperature readings to the ECU, preventing the engine management system from accurately controlling fuel delivery, turbocharger operation and emissions functions. On diesel models, incorrect readings may also interfere with diesel particulate filter regeneration, increasing soot accumulation and the risk of costly emissions system repairs.
• Replacing a worn or faulty sensor restores accurate exhaust temperature monitoring and ensures the engine and emissions systems operate efficiently. The OE Match Exhaust Gas Temperature Sensor is manufactured to OE standards using premium-quality materials, providing factory-style fitment, precise performance and long-lasting durability, helping maintain engine efficiency, emissions compliance and the reliability expected from your Porsche.
