Gas temperature sensor. Porsche 95B Macan 3.0L Diesel 4H0906088AB

Gas temperature sensor. After particulate filter. (EGT) Sensor

The OE Match Exhaust Gas Temperature (EGT) Sensor is designed to precisely monitor the temperature of exhaust gases as they leave the engine. This critical data helps the engine control module (ECM) optimize the fuel-air mixture, prevent overheating, and protect key emissions components—including the catalytic converter, DPF, and turbocharger—from excessive heat.

EGT sensors are especially important in diesel engines and high-performance applications, where accurate temperature monitoring is essential for maintaining efficiency, power, and reliability.

Symptoms of a Failing Exhaust Gas Temperature (EGT) Sensor

• Poor Fuel Economy

A faulty EGT sensor can send inaccurate temperature readings to the ECM, causing incorrect fuel-air adjustments. This leads to inefficient combustion, increased fuel consumption, and reduced overall fuel economy.

• Check Engine Light (CEL)

When the ECM detects abnormal or inconsistent temperature data, it may trigger the Check Engine light. Diagnostic trouble codes specific to the EGT sensor are often stored in the system.

• Engine Performance Issues

Incorrect temperature feedback may cause the ECM to limit engine power to avoid overheating, especially during hard acceleration or high-load conditions. This can result in sluggish performance, reduced power, or even limp-mode activation.
