Replace the steering angle sensor located in the steering column to restore proper electronic stability control and steering position feedback.
Warnings
⚠️Always disconnect the negative battery cable and wait 2 minutes before working on steering column components to prevent airbag deployment
⚠Do not rotate the steering wheel with the intermediate shaft disconnected or steering angle sensor removed, as this can damage the clockspring
⚠Steering angle sensor must be calibrated with a scan tool after installation or stability control systems will malfunction
ℹ️Mark steering wheel position relative to the column before beginning work to ensure proper alignment during reassembly

Parts
- Steering angle sensor × 1 — Use OEM specification
- Steering column cover screw grommets (if damaged) × 4 — Use OEM specification
Preparation
- Park vehicle on level surface and set parking brake
- Turn ignition off and remove key
- Ensure front wheels are in straight-ahead position
- Mark the steering wheel position at 12 o'clock with tape for reference
- Disconnect negative battery cable and wait minimum 2 minutes for airbag system to discharge
- Lower steering column to lowest position using tilt adjustment
Procedure
- 1Remove lower steering column coversUsing Torx T20 bit, remove the screws securing the lower steering column shroud. There are typically 4 screws - 2 on the bottom and 2 on the sides. Carefully pull the lower cover away from the column, disconnecting any wire clips if present. Set cover and screws aside.
- 2Remove upper steering column coverRemove the upper steering column shroud by releasing the retaining clips at the rear of the cover. Gently pull the upper cover upward and away from the steering column. Be careful not to damage the wiring harness for the multifunction switch.
- 3Disconnect steering angle sensor connectorLocate the steering angle sensor electrical connector on the steering column just below the ignition switch area. Press the connector lock tab and pull the connector straight out from the sensor. Inspect the connector terminals for corrosion or damage.
- 4Remove steering angle sensor mounting fastenersUsing Torx T30 bit, remove the 3 mounting bolts securing the steering angle sensor to the steering column. The sensor is typically mounted to a bracket that wraps around the column shaft. Keep track of any spacers or washers on the mounting bolts.Torque specMounting Bolts31 Nm (23 lb-ft)
- 5Remove steering angle sensorCarefully slide the steering angle sensor assembly off the steering column shaft. The sensor has a circular opening that fits over the shaft. Note the orientation and position of the sensor for installation of the new unit. Check for any wear marks or damage to the column shaft surface.⚠Do not rotate the steering shaft or allow it to turn during sensor removal
- 6Install new steering angle sensorPosition the new steering angle sensor over the steering column shaft, ensuring it slides on smoothly and is oriented in the same position as the original sensor. The sensor should seat flush against the mounting bracket. Verify the steering wheel is still centered and has not rotated.
- 7Install sensor mounting boltsInstall the 3 mounting bolts with any spacers or washers in their original positions. Tighten the bolts evenly in a star pattern to the specified torque of 31.0 Nm (23.0 lb-ft). Ensure the sensor assembly is secure and does not rotate on the column.Torque specMounting Bolts31 Nm (23 lb-ft)
- 8Reconnect electrical connectorReconnect the steering angle sensor electrical connector, ensuring it clicks into place securely. Verify the connector lock tab is fully engaged. Route any wire harness clips back to their original positions.
- 9Reinstall steering column coversPosition the upper steering column shroud over the column, ensuring all wiring is routed properly and not pinched. Snap the cover into place. Install the lower shroud and secure with the 4 Torx screws to 12.0 Nm (9.0 lb-ft). Verify all covers are properly seated.Torque specCover Screws12 Nm (9 lb-ft)
- 10Reconnect battery and perform calibrationReconnect the negative battery cable. Turn the ignition to ON position without starting the engine. Connect the OBD-II scan tool and access the steering angle sensor calibration function. Follow the scan tool prompts to calibrate the sensor, which typically involves turning the steering wheel from lock to lock and then centering it. Complete the calibration procedure and verify no fault codes are present.⚠Sensor calibration must be completed or stability control and ABS systems will not function properly
Reassembly
- Verify steering wheel is centered and matches the alignment mark made during preparation
- Ensure all electrical connectors are fully seated and locked
- Check that steering column covers are properly secured and all trim clips are engaged
- Return steering column to driver's preferred tilt position
Verification
- Start the engine and verify no warning lights remain illuminated on the instrument cluster, particularly the stability control or ABS lights
- Turn the steering wheel slowly from lock to lock and verify smooth operation with no binding
- Use scan tool to verify steering angle sensor is reporting accurate angle data and changes smoothly as wheel is turned
- Test drive the vehicle at low speed and verify stability control and traction control systems function normally
- Verify no diagnostic trouble codes are present in the ABS, stability control, or steering systems
