Setup, Compatibility & Care
Installation must be performed by an automotive professional to ensure the sensor is correctly seated and torqued. Ensure the exhaust system is completely cool before attempting removal of the old sensor to prevent burn injuries. When installing the new Valeo unit, verify that the thread size (M12x1.25) matches your exhaust port exactly; do not force the sensor into the housing to avoid cross-threading. The 2-pin connector should click firmly into the harness, ensuring a watertight seal. Periodic inspection of the wire harness for heat damage or fraying is recommended every time the vehicle undergoes a routine oil change or exhaust system service.
