Steering Angle Sensor Calibration Fault
The steering angle sensor calibration is incorrect or malfunctioning.
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 how far and in which direction you're turning the steering wheel. If it's off, the stability control won't know what's going on, which can mess up traction control and stability systems.
What the computer is actually seeing
The steering angle sensor sends a voltage signal indicating the angle and direction of the steering wheel. Normal operation should show a voltage change corresponding to the angle turned, typically between 0.5V (full left) to 4.5V (full right).
What a healthy reading looks like
Steering angle should normally read between +30 to -30 degrees when turning left or right, with a calibrated zero point when the vehicle is centered.
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. Inspect the wiring and connectors to the steering angle sensor for damage or corrosion. If any issues are found, repair them and clear the code to see if it returns.
- 22. Check the steering angle sensor's output using a scan tool. Observe the voltage while turning the wheel from full left to full right. Expected range should be between 0.5V and 4.5V. If outside this range, replace the sensor.
- 33. If the voltage is correct, check the vehicle’s alignment and steering rack to ensure they are functioning properly. Realign or fix as needed before recalibrating the sensor.
- 44. After repairs, use a scan tool to recalibrate the steering angle sensor. Verify that the code does not return. If it does, consider replacing the sensor.
Common causes
- Wiring issues to the steering angle sensor
- Faulty steering angle sensor
- Calibration needs to be reset after repairs
- Steering rack issues affecting sensor readings

Frequently asked questions
Is it safe to drive with this code?
It's not recommended to drive with this issue, as it can affect vehicle stability and traction control.
Will the problem come back after fixing it?
If the root cause is repaired correctly, it shouldn't return. However, if it was just a wiring issue, always check for intermittent problems.
Why does this code sometimes pair with other codes?
This code can often accompany others related to stability control and steering issues, indicating a broader problem with the steering system.
