Steering Angle Sensor Fault
There’s a problem with the steering angle sensor.
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 much you turn the steering wheel. If it’s faulty, the vehicle might behave unpredictably, especially with systems that depend on steering data.
What the computer is actually seeing
The computer expects a signal from the steering angle sensor that changes based on wheel position. If the signal is outside the normal range or missing, it triggers the code.
What a healthy reading looks like
The sensor typically outputs a voltage between 0.5V and 4.5V, corresponding to steering wheel angles from -90° to +90°.
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 for any other fault codes that may help identify the issue.
- 22. Inspect wiring and connectors going to the steering angle sensor. Look for frayed wires or corrosion; fix any issues found.
- 33. Use a scan tool to monitor the steering angle sensor data while turning the wheel. Check for expected voltage readings corresponding to angles.
- 44. If readings are erratic or out of expected range, replace the steering angle sensor and recalibrate it according to the manufacturer's specifications.
- 55. Clear the fault codes and take the vehicle for a test drive to ensure the code does not return.
Common causes
- Faulty steering angle sensor
- Wiring issues or poor connections
- Faulty steering column or steering rack module
- Calibration issue after an alignment

Frequently asked questions
Is it safe to drive with this code?
It’s generally safe, but the vehicle could experience stability control issues, especially in slippery conditions.
Will the steering angle sensor fault return after resetting?
If the sensor or wiring is truly faulty, the code will likely come back after resetting.
Why does this code appear with other codes like C0617?
These codes often trigger together if there's a common issue with the steering angle sensor or related circuitry.
