What Causes Oxygen Sensor Failure?

Oxygen sensor failure reasons are: 1. The quality of fuel added to the car is too poor, which cannot be effectively burned in the engine cylinder, resulting in more harmful substances and impurities in the exhaust gas, leading to damage of the car's oxygen sensor. 2. When the spark plug fails and cannot ignite normally, the fuel and mixed gas in the engine cylinder cannot be effectively burned, which will damage the oxygen sensor. The oxygen sensor is a key feedback sensor in the electronic fuel injection engine control system, and it is a critical component for controlling vehicle exhaust emissions, reducing environmental pollution caused by vehicles, and improving the fuel combustion quality of the car engine.
