Steering Angle Sensor Circuit Range/Performance Problem
The steering angle sensor is reporting incorrect values.
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, which tells the car how much and in which direction you are turning the steering wheel, is sending readings that don’t match what’s actually happening. This can lead to issues with systems that rely on it for stability and handling.
What the computer is actually seeing
The vehicle's computer expects the steering angle to stay within a specific range while turning. If the angle reading is outside that expected range (for example, expecting 20 degrees but receiving 60 degrees), it triggers the code.
What a healthy reading looks like
The steering angle sensor should read between -180 to 180 degrees under normal operation, with typically close to zero when the wheels are straight.
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 wiring and connectors at the steering angle sensor for damage or corrosion. Fix any found issues. Decision: If fixed, clear the code and test drive. If code returns, proceed.
- 22. Using a scan tool, check the live data from the steering angle sensor. Confirm that the angle readings correlate to the physical position of the steering wheel. Decision: If readings are inconsistent, replace the sensor. If readings are correct, look for further issues.
- 33. Inspect the power steering system for leaks or issues, ensuring proper operation. Decision: If power steering is failing, repair it. If not, continue with sensor replacement.
Common causes
- Faulty steering angle sensor
- Wiring issues in the sensor circuit
- Poor connection at the sensor or computer
- Faulty power steering system affecting sensor readings

Frequently asked questions
Can I still drive the vehicle?
Yes, but it may affect handling and stability, so drive cautiously until fixed.
Is this likely to come back after resetting?
If the underlying issue isn’t resolved, it will likely return.
Why does this code appear with other codes?
It often relates to other systems that use the steering angle sensor for operations like traction control or ABS.
