This procedure replaces the steering angle sensor located on the steering column of the 2023 Chevrolet Bolt EUV, which is essential for electronic stability control and driver assistance systems.

Warnings

Tools required

Parts

• Steering angle sensor × 1 — Use OEM specification
• Steering column coupling bolt (if reuse not permitted) × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and set parking brake
2. Turn ignition off and remove key/fob from vehicle
3. Center the steering wheel and note the position
4. Disconnect 12V auxiliary battery negative terminal and wait minimum 2 minutes
5. Ensure front wheels are pointing straight ahead

Procedure

1. 1

   Remove lower steering column covers
   Remove the lower dash trim panel below the steering column. Remove the fasteners securing the upper and lower steering column covers using a 10mm socket. Separate the covers and set aside. Disconnect any electrical connectors for the cover-mounted switches if present.
2. 2

   Access steering angle sensor
   Locate the steering angle sensor on the steering column just below the steering wheel. It is a black module with an electrical connector. Note the sensor orientation and any alignment marks before removal.
   ℹ️Take a photo of the sensor position and wiring routing for reference during installation.
3. 3

   Disconnect sensor electrical connector
   Press the locking tab on the steering angle sensor electrical connector and carefully disconnect it from the sensor. Move the wiring harness aside to provide clearance for sensor removal.
4. 4

   Remove steering column intermediate shaft coupling bolt
   Locate the intermediate shaft coupling bolt connecting the steering column to the intermediate shaft. Mark the relationship between the shafts with a paint marker for alignment reference. Using a 13mm socket, remove the coupling bolt completely. Do not allow the shafts to separate more than necessary.
   ⚠Support the intermediate shaft to prevent it from dropping or rotating after bolt removal.

5. 5

   Remove steering angle sensor mounting fasteners
   Remove the mounting bolts or screws securing the steering angle sensor to the steering column using the appropriate socket. Most sensors use either 10mm bolts or Torx screws. Keep track of all hardware for reinstallation.
6. 6

   Remove old steering angle sensor
   Carefully slide the steering angle sensor off the steering column shaft. Note the position of any alignment features, slots, or keyed surfaces. Inspect the steering column shaft for damage or debris and clean if necessary.
7. 7

   Install new steering angle sensor
   Position the new steering angle sensor on the steering column shaft, ensuring any alignment keys or slots are properly engaged. The sensor should slide on smoothly and sit flush against the mounting surface. Verify correct orientation by comparing to photos taken during disassembly.
   ⚠Ensure the sensor internal gears mesh properly with the steering shaft. Improper installation will result in incorrect angle readings.
8. 8

   Secure sensor mounting fasteners
   Install and hand-tighten the steering angle sensor mounting bolts or screws. Torque the fasteners to specification in a cross pattern if multiple fasteners are present. Verify the sensor is secure and does not rotate on the shaft.

   Mounting Bolts27 Nm (20 lb-ft)
9. 9

   Reconnect intermediate shaft coupling
   Align the marks made during disassembly on the steering column and intermediate shaft. Install the coupling bolt and torque to specification. Verify the shafts are properly engaged and aligned.
   ⚠Misalignment of the intermediate shaft will cause steering wheel off-center condition and incorrect sensor readings.

10. 10

    Connect sensor electrical connector
    Route the wiring harness back to the steering angle sensor and connect the electrical connector. Ensure the connector locks securely with an audible click. Verify no wires are pinched or under tension.
11. 11

    Reinstall steering column covers
    Reinstall the upper and lower steering column covers, ensuring all clips and tabs are properly engaged. Install and torque the cover screws to specification. Reconnect any electrical connectors for cover-mounted switches.
    Torque spec

    Cover Screws11 Nm (8 lb-ft)
12. 12

    Reconnect battery and calibrate sensor
    Reconnect the 12V auxiliary battery negative terminal. Turn the ignition on without starting the vehicle. Using a professional scan tool, access the steering angle sensor module and perform the steering angle sensor calibration procedure. Follow the scan tool prompts, which typically involve turning the steering wheel lock-to-lock and returning to center.
    ⚠️Failure to properly calibrate the steering angle sensor will result in disabled electronic stability control, traction control, and driver assistance features. The vehicle may be unsafe to drive.

Reassembly

1. Verify all trim panels and covers are properly secured
2. Confirm steering wheel turns smoothly with no binding or unusual noises
3. Ensure all electrical connectors are locked and secured

Verification

• Start the vehicle and verify no warning lights remain illuminated on the instrument cluster, specifically the ESC, traction control, or steering system warnings
• Using the scan tool, verify the steering angle sensor shows correct readings (0 degrees at center, changes appropriately when wheel is turned)
• Perform a test drive at low speed in a safe area, turning the wheel lock-to-lock to verify proper operation of stability control and driver assistance systems
• Re-scan for diagnostic trouble codes and verify none are present related to the steering angle sensor or related systems
• Verify steering wheel is centered when driving straight ahead
