Steering Angle Sensor Range/Performance
The steering angle sensor is reading out of range or is not functioning 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 angle sensor tells the computer how far and in which direction you're turning the wheel. If it's not working right, the computer can't adjust the vehicle's stability or traction control properly.
What the computer is actually seeing
The computer expects the steering angle sensor to output a voltage between 0.5 to 4.5 volts, corresponding to a turn angle of -30 to +30 degrees. If the output is outside this range, the code sets.
What a healthy reading looks like
Normal operation should show a voltage reading from 0.5V (full left) to 4.5V (full right), with 2.5V representing the neutral steering position.
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 steering angle sensor wiring for frays or damage. Check connectors for corrosion or loose connections. If bad, repair/replace as needed. Decision: Were any issues found? (Yes - fix the wiring/connectors; No - proceed to next step.)
- 22. Use a scan tool to read live data from the steering angle sensor. Check the voltage output while turning the wheel. It should be between 0.5V and 4.5V. Decision: Is the output normal? (Yes - continue testing; No - sensor may be faulty.)
- 33. If the sensor output is out of range, disconnect the sensor and check its resistance. Compare to specifications (usually around 1k ohms). Decision: Is resistance within specs? (Yes - suspect wiring or ECM issue; No - replace the steering angle sensor.)
- 44. After replacing the sensor, reset any stored codes in the ECU and perform a steering angle calibration using a diagnostic tool. Decision: Are any codes still present after calibration? (Yes - further diagnosis needed; No - issue resolved.)
Common causes
- Faulty steering angle sensor
- Wiring harness issues
- Bad connectors
- Faulty vehicle stability system
- Software calibration issues

Frequently asked questions
Is it safe to drive with this code?
It may be drivable, but you can lose stability control features, which is a safety concern.
Will this code come back after clearing it?
If the underlying issue isn't fixed, the code will likely return after driving.
Why does this code sometimes pair with ABS codes?
Both the steering angle sensor and ABS relate to vehicle stability, so a fault in one can trigger faults in the other.
