Where to find your model number
- Toyota: Use your 17-character VIN. It's on the driver-side dashboard at the base of the windshield and on the driver's door jamb sticker. The year is in the 10th character. Also check your registration or the owner's manual.
General manufacturer guidance: exact label position can vary by model.

Installation guide - Replacing an engine or wheel sensor
General guidance for this part type - always follow your device manual- Socket set (oxygen sensors need an O2 sensor socket)
- Penetrating oil
- OBD2 scanner
- If the same code returns, check the connector and wiring before suspecting the new sensor.
- 1Make it safe. Engine off and cool (exhaust parts stay hot for a long time). Raise the car on axle stands if the sensor is underneath.
- 2Follow the wire. Trace the sensor's wire to its connector, unplug it and unclip the wire from its holders, noting the route.
- 3Remove the old sensor. Soak rusty threads with penetrating oil first. Oxygen sensors unscrew with the O2 socket; wheel speed and crank sensors usually have one bolt and twist out. Clean rust from the mounting hole.
- 4Fit the new sensor. Keep anti-seize off an oxygen sensor's tip (new ones often come pre-coated on the threads). Lightly oil an O-ring, seat the sensor fully and route the wire through the original clips, away from hot or moving parts.
- 5Clear codes and test. Reconnect, clear the fault codes with an OBD2 scanner and drive to check the warning light stays off.
This is general guidance for the part type, not a model-specific procedure. If the part does not fit without force, stop and recheck compatibility.
