Cleaning an oxygen sensor involves the following steps: 1. Remove the oxygen sensor from the vehicle; 2. Dissolve ferric chloride in water and mix it with hydrochloric acid; 3. Soak the oxygen sensor in the prepared solution for 10 to 15 minutes; 4. After soaking, wipe it clean with a clean cloth until the oxygen sensor turns white. The oxygen sensor is a critical feedback sensor in the electronic fuel injection engine control system, playing a key role in controlling vehicle exhaust emissions, reducing environmental pollution, and improving the fuel combustion quality of the car engine. Oxygen sensors are typically installed on the engine's exhaust pipe.
