Steps
Raise the vehicle and remove the wheel
Park on level ground, loosen the wheel nuts slightly, and raise the vehicle at an approved point. Support it on jack stands before removing the wheel to reach the sensor behind the wheel-well liner.
Remove the old revolution sensor
Release the wheel-well panel clips and move the panel aside. Unplug the sensor harness, remove its 10 mm retaining bolt, and carefully pry the sensor from its mounting bore without damaging the connector or sealing surface.
Install the replacement sensor
Seat the new sensor squarely in its bore and reinstall the retaining bolt. Reconnect the harness until its lock engages and refit the wheel-well panel clips securely.
Reinstall the wheel and verify
Mount the wheel and start the nuts by hand. Lower the vehicle and tighten the wheel nuts in a star pattern to the vehicle's specification. Start the engine and check for a warning light or continuing transmission symptoms.
Check your vehicle’s repair manual for exact specifications and fit.
