Steps
Disconnect the sensor
Let the engine and exhaust cool completely. Unplug the sensor connector, release its wiring retainer, and note the lead's original route.
Remove the old sensor
Fit an oxygen-sensor socket over the sensor and loosen it from the exhaust. Inspect the bung threads and keep dirt from entering the opening.
Install the replacement sensor
Start the new sensor by hand to prevent cross-threading. Tighten it to the vehicle specification and avoid contaminating its sensing tip.
Reconnect and inspect
Reconnect the plug and secure the lead in its original retainers. Start the engine and inspect for exhaust leaks while confirming the wiring is clear of hot parts.
Check your vehicle’s repair manual for exact specifications and fit.
