Product Description:

Upstream Oxygen sensor
OE NO.:  32253666 30713864

Applicable vehicle type: For Volvo

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.”

The automotive oxygen sensor is a sensing component installed on the engine exhaust pipe, used to detect the oxygen concentration in the exhaust gas. It monitors the air-fuel ratio within the engine and transmits feedback signals to the car's computer, thereby enabling precise control of fuel injection volume, reducing fuel consumption and exhaust pollutant emissions, and improving engine performance.

Common Faults and Detection

• Common Faults: Include poisoning (such as lead poisoning, silicon poisoning), carbon buildup, ceramic fracture, broken heater resistance wire, and broken internal electrode lead. These faults can lead to problems such as increased engine fuel consumption, unstable idle, and excessive exhaust emissions.
• Detection Methods: Visual inspection can be used, where the color of the oxygen sensor edge can be observed to determine the fault. For example, black may indicate carbon buildup, brown may indicate lead poisoning, and white may indicate silicon poisoning. Voltage detection can also be employed, measuring the feedback voltage of the oxygen sensor and the resistance of the heater to determine if it is functioning normally.
