The exhaust pipe of the car is equipped with two oxygen sensors, which are located in the front and rear positions, known as the front oxygen sensor and the rear oxygen sensor. Although their functions are similar, each has its own emphasis. The front oxygen sensor is mainly responsible for monitoring the combustion efficiency of the engine and the oxygen content in the exhaust gas.
Once the relevant data is detected, it will send this information in the form of a signal to the engine's computer board, which in turn adjusts the amount of fuel injected by the engine to ensure that the engine is running in the optimal state. It is worth noting that the front oxygen sensor usually starts working when the temperature reaches about 400 degrees.
