Steering Angle Sensor Range/Performance Problem
Problem with the steering angle sensor's performance or range.
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 tracks how far the steering wheel is turned. If it's not reading correctly, the vehicle may act unpredictably while turning.
What the computer is actually seeing
The sensor typically sends a voltage signal proportional to the steering angle. If the angle is off by more than 5 degrees from expected, a fault code sets.
What a healthy reading looks like
0 to 5 volts at the steering angle sensor, based on the wheel position; voltages correlate with angles from -180 to +180 degrees.
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 connector for corrosion or damage. Repair as needed.
- 22. Check the wiring harness from the sensor to the ECM for breaks or shorts. Fix any found issues.
- 33. Verify the alignment of the steering wheel. Ensure it is centered when the vehicle is traveling straight. Adjust if needed.
- 44. Use a scan tool to read live data from the steering angle sensor. Check if the angle readings correspond to the wheel position. Should be within 5 degrees.
- 55. If issues persist, test or replace the steering angle sensor based on live data readings and electrical tests.
Common causes
- Dirty or corroded connectors at the steering angle sensor
- Faulty steering angle sensor
- Misalignment of the steering wheel sensor
- Damaged wiring harness between the sensor and the ECM

Frequently asked questions
Is it safe to drive with this code?
It's drivable, but handling may feel off, especially during turns. Get it fixed soon.
Will this code reset itself after a repair?
Yes, it should clear once the problem is resolved and the computer doesn't see the fault anymore.
Why is this related to other codes?
It's common for steering and stability-related systems to influence each other; failures in one can trigger faults in others.
