Technical specifications

Installation requirements

Professional installation is recommended. Work on a cool exhaust, disconnect the sensor plug, and remove the old unit with a slotted sensor socket. Fit the new sensor finger-tight first, then torque to specification, keeping the cable clear of hot or moving parts. Clear stored codes and check live sensor data after a test drive.

A worn sensor may cause increased fuel use, rough running, failed emissions checks or a warning light.

Fitment checks before ordering

The OE numbers grouped here differ in wire count, cable length and sensor position, so it is unclear which exact variant this item is. Please quote the number on your current sensor or your VIN and engine code before ordering.
