Exhaust Gas Temperature Sensor

Introduction

An Exhaust Gas Temperature (EGT) Sensor, also known as an Exhaust Temperature Sensor, is a sensor used to monitor the temperature of exhaust gases in an internal combustion engine. The sensor is located in the exhaust system and measures the temperature of the exhaust gases as they exit the engine.

The EGT sensor provides valuable information to the engine control system, which uses the data to adjust the air/fuel mixture and timing to optimize engine performance and reduce emissions. The sensor can also help detect potential problems with the engine, such as a clogged exhaust system or a malfunctioning combustion chamber.

EGT sensors are commonly used in diesel engines, as they tend to run hotter than gasoline engines due to their higher compression ratio. They are also used in high-performance gasoline engines, where monitoring exhaust gas temperature is important for optimizing engine performance.
