Steps
Raise the vehicle and remove the wheel
Loosen the lug nuts while the tire is on the ground, then lift and support the vehicle securely. Remove the wheel to reach the sensor and its wiring.
Remove the old sensor
Remove the sensor retaining bolt and carefully ease the sensor from the knuckle. Release its harness from each clip and unplug the connector without pulling on the wires.
Install and route the replacement
Seat the replacement sensor fully and secure its fastener. Reconnect the plug and route the wire through the original retainers, clear of moving or hot parts.
Reinstall the wheel and check
Refit the wheel and tighten the lug nuts in a crossing pattern to specification. Confirm the ABS warning lamp goes out after startup and check for diagnostic codes if it remains on.
Check your vehicle’s repair manual for exact specifications and fit.
