Steering Wheel Sensor Calibration Fault
The steering wheel position sensor signal is out of range or not calibrated properly.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The steering wheel angle sensor isn't communicating correctly with the computer, which can mess up steering assistance and stability control systems.
What the computer is actually seeing
The computer expects the Steering Angle Sensor to report angles between -30° and +30° when turned, and it should return a value within that range depending on how far the wheel is turned. If it sees values outside this range, it triggers this code.
What a healthy reading looks like
Steering angle should range from -30° (full left) to +30° (full right) with a zero angle at center. Sensor voltage should stay between 0.5V (full left) and 4.5V (full right).
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Check the steering wheel position sensor wiring and connectors for damage or corrosion. Are they intact? If not, repair or replace as necessary.
- 22. Verify the sensor output with a scan tool. Is the steering angle within the expected range (-30° to +30°)? If no, continue to the next step.
- 33. Perform a sensor calibration using a scan tool as per the manufacturer's instructions. Did the calibration complete successfully? If yes, clear codes and test drive the vehicle. If not, replace the sensor.
- 44. Check for any other codes present. Are there related codes (like other steering or stability issues)? If yes, diagnose those first before moving forward.
Common causes
- Faulty steering wheel position sensor
- Improperly calibrated sensor
- Wiring issues – damaged or corroded connectors
- Faulty Electronic Control Unit (ECU)
- Incorrect alignment after repairs

Frequently asked questions
Is it safe to drive with this code?
It's moderate; you can drive but pay attention to steering feel and stability. Fix it soon.
Why do I keep getting this code?
Usually due to a faulty sensor or misalignment after steering work. Make sure to check sensor calibration and wiring.
Will this code return after repairs?
If all repairs are done correctly and calibration is successful, it shouldn't return.
