Steering Angle Sensor Circuit Range/Performance Problem
The steering angle sensor is malfunctioning or out of 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 tells the computer where the wheels are pointing. If it's not working right, the computer can’t control things like stability or traction properly.
What the computer is actually seeing
The computer expects the sensor to output a voltage from 0.5 to 4.5 volts corresponding to the steering angle. If it sees a value outside of this range or doesn't see any change as you turn the wheel, it triggers this code.
What a healthy reading looks like
0.5V (hard left) to 4.5V (hard right), with a smooth transition as the wheel is turned.
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 for damage or corrosion at the steering angle sensor and the ECM. Repair or clean as needed.
- 22. Check the steering angle sensor output voltage at the sensor connector while turning the steering wheel. Voltage should smoothly transition from 0.5V to 4.5V. If not, the sensor is likely faulty.
- 33. Compare the sensor data with a reliable scan tool or PIDs while driving (steering angle vs actual vehicle direction). If the readings differ significantly, consider replacing the steering angle sensor.
- 44. Clear the code and take the vehicle for a test drive to see if the code returns. If it does and all checks passed, replace the steering angle sensor.
Common causes
- Faulty steering angle sensor
- Wiring issues or loose connectors
- Faulty steering column or rack
- Corrosion in sensor connections

Frequently asked questions
Is it safe to drive with this code?
It's drivable but be cautious. You may experience reduced traction control and stability assist.
Will this code come back after resetting?
If there’s a persistent issue, yes, the code will typically return.
What if the steering feels normal?
The steering can feel normal while the sensor is faulty. Always check the sensor's output.
