Steps
Disconnect power and remove the wheel
Switch off the ignition and disconnect the negative battery cable. Loosen the rear lug nuts slightly, raise and support the vehicle on jack stands, then remove the wheel to expose the sensor and harness route.
Access the sensor wiring
In the trunk, lift the carpet and remove the two plastic retainers and access cover. Disconnect the sensor harness and push its rubber grommet down through the floor opening. Remove the sensor's 10 mm bolt at the wheel and work the sensor free carefully.
Remove the old harness
Lower the heat shield by removing its two fasteners, then release the wheel-speed harness retainers. Pull the sensor and harness out as one assembly without snagging the brake line or damaging the floor grommet.
Install the new sensor and harness
Feed the replacement harness through the floor opening and seat the rubber grommet. Route the wire through its original retainers, reinstall the heat shield and sensor bolt, then reconnect the harness in the trunk and refit its cover and carpet.
Reinstall the wheel and verify ABS
Mount the wheel and start the lug nuts by hand. Lower the vehicle and tighten them in a star pattern to the vehicle's specification. Reconnect the battery, start the vehicle, and check the ABS warning indicator; scan for codes if it remains on.
Check your vehicle’s repair manual for exact specifications and fit.
