Our advantages:
The R pre-lubricated threads enable the quick and easy replacement of the oxygen sensor probe. 
Due to the adjusted cable length, this probe is tailor-made for each type of vehicle.
The connectors fit perfectly, just as they do in the original equipment.

Working Principle:
The oxygen sensor detects the oxygen concentration in exhaust gas by generating voltage. A typical oxygen sensor uses a zirconia electrode, which becomes conductive at high temperatures. The sensor divides the exhaust gas flow into two parts: one is outside air, and the other is the exhaust gas. Due to the difference in oxygen concentration between these two parts, the zirconia electrode generates an electromotive force (EMF) between them. The ECU uses this EMF to determine whether the air-fuel mixture is lean or rich.

Maintenance and Faults:
The oxygen sensor may fail due to carbon buildup, contaminants, or aging after long-term use. Common symptoms include reduced fuel economy, increased emissions, and an illuminated engine warning light. Regular inspection and replacement of the oxygen sensor are important measures to maintain engine performance and reduce pollution.

Conclusion:
In summary, the oxygen sensor plays a critical role in a vehicle’s fuel management and emission control system, ensuring optimal engine operation while effectively reducing harmful exhaust emissions.
