Does the Oxygen Sensor Need Regular Cleaning?

[BennettRose]

The oxygen sensor requires regular cleaning. Its function is to measure whether there is excess oxygen in the exhaust after engine combustion, convert the oxygen content into a voltage signal, and transmit it to the engine computer. This enables the engine to achieve closed-loop control targeting excess air, ensuring that the three-way catalytic converter has high conversion efficiency for pollutants such as hydrocarbons, carbon monoxide, and nitrogen oxides in the exhaust, thereby maximizing the conversion and purification of emission pollutants. The working principle of the oxygen sensor is as follows: it uses a ceramic sensing element to measure the oxygen potential in the vehicle's exhaust pipe, calculates the corresponding oxygen concentration based on the chemical equilibrium principle, and achieves the purpose of monitoring and controlling the combustion air-fuel ratio to ensure product quality and compliance with exhaust emission standards as a measuring component.
