Steering Angle Sensor Performance Problem
There's a problem with the steering angle sensor's performance.
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 you turn the steering wheel. If it’s not working right, the computer can’t tell how much you’re steering, which can cause issues like stability control or antilock brakes malfunctioning.
What the computer is actually seeing
The computer expects to see an angle reading that changes smoothly between -90 to 90 degrees as you turn the wheel. If it notices an unexpected reading, like an abrupt jump or stays constant when the wheel is turned, it triggers the code.
What a healthy reading looks like
About 0.5 to 4.5 volts when centered, varying smoothly between 0 to 5 volts as you steer.
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 column wiring and connectors for damage or corrosion. If damaged, repair or replace as necessary. Decision point: Are connectors clean and intact?
- 22. Check the alignment of the steering angle sensor. If misaligned, adjust. Decision point: Is the sensor properly aligned?
- 33. Using a scan tool, monitor live data from the steering angle sensor. Turn the wheel and see if the readings fluctuate correctly. Decision point: Do the readings change smoothly with wheel movement?
- 44. If readings are faulty, replace the steering angle sensor. Decision point: Has the code cleared after replacing the sensor?
Common causes
- Faulty steering angle sensor
- Wiring issues to the sensor
- Bad connections or corrosion
- Faulty clockspring (in some vehicles)

Will this code come back after I reset it?
If the underlying issue isn't fixed, yes, the code will likely return.
Why does this code appear with ABS warnings?
They share data; issues with the steering angle sensor can affect ABS performance.
