The exhaust temperature sensor is a sensor that detects the exhaust temperature of the engine, which measures the temperature in the exhaust pipe and passes this data to the car's computer system. The exhaust temperature sensor is usually located in the exhaust pipe in order to measure the exhaust temperature, and this data can be used to monitor the operation of the engine and adjust it if necessary. The exhaust temperature sensor is an important part of the computer system of the modern car, which can help the driver to maintain the optimal operation of the engine and ensure the safe operation of the vehicle in the high temperature environment.
