Steering Angle Sensor

Replace the steering angle sensor located in the steering column assembly to restore proper electronic stability control and steering position feedback.

Warnings

Tools required

Parts

• Steering angle sensor × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and set parking brake
2. Turn ignition off and remove key
3. Disconnect negative battery terminal and wait minimum 3 minutes
4. Center the steering wheel and ensure front wheels are pointing straight ahead
5. Set driver's seat to full rear position for access

Procedure

1. 1

   Remove lower steering column covers
   Remove 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 spec

   Cover Screws10 Nm (8 lb-ft)
2. 2

   Disconnect electrical connectors
   Locate 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.
3. 3

   Remove steering angle sensor mounting
   Locate 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 spec

   Mounting Bolts26 Nm (19 lb-ft)
4. 4

   Remove steering angle sensor
   Carefully 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.
5. 5

   Install new steering angle sensor
   Position 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.
6. 6

   Secure sensor mounting bolts
   Install 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 spec

   Mounting Bolts26 Nm (19 lb-ft)
7. 7

   Reconnect electrical connector
   Route 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.
8. 8

   Reinstall steering column covers
   Position 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 spec

   Cover Screws10 Nm (8 lb-ft)
9. 9

   Reconnect battery and calibrate sensor
   Reconnect 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

1. Verify all trim panels and covers are securely fastened
2. Return driver's seat to normal position
3. 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
