Steering Angle Sensor Calibration Fault
The system detected an issue with the steering angle sensor calibration.
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 angle sensor measures the position of the steering wheel to help with vehicle stability and control. If there's a fault, it means the vehicle doesn't know how much you're turning the wheel, which can affect safety features like traction control.
What the computer is actually seeing
The module expects a changing voltage value from the steering angle sensor as the wheel turns. This value typically ranges from 0.5V to 4.5V depending on the angle. If the value doesn't change as expected during a calibration procedure, the system triggers a fault.
What a healthy reading looks like
Expected voltage signals from the steering angle sensor should be between 0.5V (full left) to 4.5V (full right) with a center position around 2.5V when the wheel is straight.
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 steering angle sensor wiring and connectors for damage or corrosion. Decision: If damaged, repair or replace.
- 22. Use a scanner to read live data from the steering angle sensor. Check voltage output. Decision: If out of expected range (0.5V - 4.5V), suspect a faulty sensor and replace it.
- 33. If the sensor voltage is normal, attempt to recalibrate the steering angle sensor using the scan tool. Decision: If calibration fails, further inspect the steering control module.
- 44. After repairs, clear the fault codes and test drive to verify the issue is resolved.
Common causes
- Faulty steering angle sensor
- Wiring issues or damaged connector
- Calibration not performed after vehicle repairs or battery reset
- Faulty steering control module
Typical repair cost
$$ (200 - 500)

Frequently asked questions
Is it safe to drive with this code?
While you can drive, the vehicle's traction control and stability features may not work properly, so it’s best to fix it soon.
Will this issue come back after repair?
If the sensor is replaced and everything is calibrated properly, it shouldn't come back. But check connections regularly.
Why does this code appear after a battery reset?
After resetting the battery, the system may lose calibration data. A recalibration is necessary for accurate readings.
