Product Description:

Electronic Oxygen Sensor

OE NO.: 30774570 30751865

Applicable vehicle type: For VO LVO

An automotive oxygen sensor is an electronic sensor installed in the engine exhaust system to monitor the oxygen content in exhaust gases. Its English names are “Oxygen Sensor” or “Lambda Sensor.”

Oxygen sensors can be classified into narrow-range and wide-range types based on their signal characteristics. Narrow-range oxygen sensors can only determine whether the air-fuel ratio is rich or lean, while wide-range oxygen sensors can know the specific numerical value of the air-fuel ratio, enabling more precise control. They are suitable for advanced engine technologies such as direct injection and lean burn.

Common Faults and Their Impacts

• Fault Causes: The working environment of the oxygen sensor is harsh, and faults may occur due to factors such as carbon deposit coverage, chemical contamination (e.g., lead, silicon in inferior fuel), aging wiring, loose connectors, or aging ceramic components.
• Fault Impacts: Once a fault occurs in the oxygen sensor, it will increase engine fuel consumption and exhaust pollution, and result in fault phenomena such as unstable idle speed, misfiring, and surging.
