Exhaust Gas Temperature Sensor. Porsche 958 Cayenne Diesel / 95B Macan Diesel / 970 Panamera Diesel  ❭  95860668870

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

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.
