Replace the oxygen sensor once for vehicles with over 100,000 kilometers. Below is relevant information about the oxygen sensor: Definition: 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 caused by vehicles, and improving the fuel combustion quality of the car engine. Oxygen sensors are installed on the engine exhaust pipe. Working Principle: Under certain conditions (high temperature and platinum catalysis), the oxygen concentration difference on both sides of the zirconia is utilized to generate a potential difference. The greater the concentration difference, the larger the potential difference.
