Replace the steering angle sensor located in the steering column assembly to restore proper electronic stability control and steering position feedback.
Warnings
⚠️Disconnect the negative battery terminal and wait at least 3 minutes before working on steering column components to allow airbag system capacitors to discharge.
⚠The steering angle sensor must be calibrated using a scan tool after installation or the electronic stability control and lane keeping systems will not function properly.
⚠Do not rotate the steering wheel with the intermediate shaft disconnected as this can damage the clockspring.

Parts
- Steering angle sensor × 1 — Use OEM specification
Preparation
- Park vehicle on level surface and set parking brake
- Turn ignition off and remove key
- Disconnect negative battery terminal and wait minimum 3 minutes
- Center the steering wheel and ensure front wheels are pointing straight ahead
- Set driver's seat to full rear position for access
Procedure
- 1Remove lower steering column coversRemove the lower dashboard trim panel below the steering column. Remove the Phillips head screws securing the upper and lower steering column covers. Carefully separate the cover halves and remove them to expose the steering column assembly.Torque specCover Screws10 Nm (8 lb-ft)
- 2Disconnect electrical connectorsLocate the steering angle sensor connector on the steering column assembly. Press the locking tab and disconnect the electrical connector from the sensor. Note the routing of the wiring harness for reinstallation.
- 3Remove steering angle sensor mountingLocate the mounting bolts securing the steering angle sensor to the steering column. Remove the bolts using the appropriate socket. The sensor is typically mounted with 2-3 bolts on the 2015 Forte.Torque specMounting Bolts26 Nm (19 lb-ft)
- 4Remove steering angle sensorCarefully slide the steering angle sensor off the steering shaft. Note the orientation and position of the sensor on the shaft, including any alignment marks or tabs. Keep the sensor away from magnetic fields and impacts.
- 5Install new steering angle sensorPosition the new steering angle sensor onto the steering shaft, ensuring proper alignment with any locating tabs or marks. Verify the steering wheel is still centered and front wheels are straight before proceeding. Slide the sensor fully onto the shaft until it seats properly.
- 6Secure sensor mounting boltsInstall the steering angle sensor mounting bolts and tighten to specification in a cross pattern if multiple bolts are present. Ensure the sensor is properly seated against the mounting surface before final torque.Torque specMounting Bolts26 Nm (19 lb-ft)
- 7Reconnect electrical connectorRoute the wiring harness as noted during removal and reconnect the electrical connector to the steering angle sensor. Ensure the locking tab clicks into place securely. Verify no wires are pinched or strained.
- 8Reinstall steering column coversPosition the lower and upper steering column covers over the column assembly. Install the cover screws and tighten to specification. Reinstall the lower dashboard trim panel.Torque specCover Screws10 Nm (8 lb-ft)
- 9Reconnect battery and calibrate sensorReconnect the negative battery terminal. Connect the scan tool to the vehicle's OBD-II port. Turn the ignition to ON position (do not start engine). Access the steering angle sensor calibration function in the scan tool and perform the zero-point calibration procedure according to the tool's instructions. This typically requires confirming the steering wheel is centered.
Reassembly
- Verify all trim panels and covers are securely fastened
- Return driver's seat to normal position
- Clear any diagnostic trouble codes using the scan tool after calibration is complete
Verification
- Start the engine and verify the steering angle sensor communication is active via scan tool (should show changing angle values as steering wheel is turned)
- Verify no warning lights are illuminated on the instrument cluster (ESC, ABS, or steering system warnings)
- Test drive the vehicle at low speed in a safe area and verify electronic stability control and traction control systems function normally
- Confirm steering angle readings on scan tool return to zero when steering wheel is centered
- Verify lane keeping assist and other driver assistance features function properly if equipped
