Can White Vinegar Clean an Oxygen Sensor?

[McAdam]

White vinegar can clean an oxygen sensor, but the effect is not significant. It is only suitable for cleaning slightly dirty oxygen sensors because white vinegar is a weak acid. If using white vinegar for cleaning, it should be heated before use. Typically, ferric chloride and hydrochloric acid solutions are used for soaking and cleaning oxygen sensors. The automotive oxygen sensor is a critical feedback sensor in the electronic fuel injection engine control system. It is a key component for controlling vehicle exhaust emissions, reducing environmental pollution, and improving the fuel combustion quality of the car engine. Oxygen sensors are installed on the engine exhaust pipe. The oxygen sensor uses a ceramic sensing element to measure the oxygen potential in various heating furnaces or exhaust pipes, calculates the corresponding oxygen concentration based on the chemical equilibrium principle, and monitors and controls the air-fuel ratio in the furnace combustion to ensure product quality and compliance with exhaust emission standards.
