Product Description:

O2 sensor
OE NO.: 30637519 30637837

Applicable vehicle type: For Volvo

The automotive oxygen sensor or “Lambda Sensor” is a critical component in the vehicle emission control system, primarily used to monitor the oxygen content in exhaust gases in order to achieve precise control of the engine's air-fuel ratio.

Installation Location:

• Front Oxygen Sensor: Typically installed on the exhaust pipe between the engine exhaust manifold and the three-way catalytic converter. It is used to monitor the original exhaust composition after engine combustion, providing the ECU with real-time feedback on the air-fuel mixture concentration, which serves as the primary basis for closed-loop control.
• Rear Oxygen Sensor: Installed on the exhaust pipe after the three-way catalytic converter. Its main function is to monitor the working efficiency of the three-way catalytic converter. By comparing the signals from the front oxygen sensor and the rear oxygen sensor, the ECU can determine whether the three-way catalytic converter is operating normally.
