The reason for the car not shaking when the oxygen sensor is unplugged but shaking when installed is that the oxygen sensor is damaged. In this case, it is necessary to go to a 4S shop or auto repair shop to replace the oxygen sensor. The following is the relevant introduction: The impact of a damaged front oxygen sensor on the car: Excessive exhaust emissions; deterioration of engine conditions; the vehicle stalls at idle; inaccurate engine operation and reduced power; the engine computer cannot accurately judge the mixture condition; affects the normal operation of the three-way catalytic converter. The role of the oxygen sensor: The car oxygen sensor is a key feedback sensor in the electronically controlled fuel injection engine system. It is a key component to control car exhaust emissions, reduce car pollution to the environment, and improve the fuel combustion quality of the car engine. The oxygen sensor is installed on the engine exhaust pipe. Maintenance of the oxygen sensor: Check the working status of the oxygen sensor every 30,000 kilometers. If it is aging or failing, clean or replace the oxygen sensor in time.
