An exhaust gas temperature sensor in a car is a vital component that measures the temperature of the exhaust gases as they exit the combustion chamber.

It plays a crucial role in monitoring the engine's performance and emissions. The sensor is typically located in the exhaust manifold or the exhaust pipe.

The exhaust gas temperature sensor works by using a thermistor, which is a type of temperature-sensitive electrical resistance device.

The thermistor detects the heat generated by the combustion process and converts it into an electrical signal. This signal is then sent to the engine control unit (ECU), which uses the data to adjust the fuel mixture and optimize the engine's performance.

By monitoring the exhaust gas temperature, the sensor helps prevent engine damage caused by overheating and ensures efficient fuel combustion, reducing harmful emissions.
