Steering Angle Sensor Circuit Range/Performance Problem
There's a problem with the steering angle sensor signal.
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 the steering wheel is turned, and if it's off, it could affect handling and safety.
What the computer is actually seeing
The PCM sees a steering angle reading that is outside the expected range, typically below -20 degrees or above 20 degrees during normal driving conditions.
What a healthy reading looks like
Steering angle sensor should typically read between -30 to 30 degrees when the wheel is turned; values out of this range are flagged.
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 visible damage or corrosion.
- 22. Check connector integrity; ensure pins are not bent or corroded.
- 33. Measure voltage at the steering angle sensor connector. Expected: 5V reference; if no voltage, check PCM power and grounds.
- 44. Monitor the steering angle sensor parameter with a scan tool while turning the wheel. Should show smooth changes between -30 and 30 degrees.
- 55. If readings are erratic or out of range, replace the steering angle sensor and recalibrate it if necessary.
Common causes
- Faulty steering angle sensor
- Wiring issues (shorts or opens)
- Corroded connectors
- Calibration issue after wheel alignment

Frequently asked questions
Is it safe to drive with this code?
Yes, but you should fix it soon, since it can affect vehicle handling and stability.
Will this code come back after clearing?
It might if the underlying issue isn't resolved, such as a wiring problem or a bad sensor.
Why does this code appear with other codes?
It often pairs with other steering or stability control codes because they can share the same circuits or sensor inputs.
