Steering Wheel Position Sensor Performance
The steering wheel position sensor is reporting an issue.
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 sensor that tracks how much you turn the steering wheel is malfunctioning, which can impact steering performance and traction control.
What the computer is actually seeing
The PCM expects a smooth voltage signal between 0.5V and 4.5V from the steering wheel position sensor as you turn the wheel, but it's getting erratic or outside this range.
What a healthy reading looks like
Steering wheel angle should vary from approximately -180 degrees to +180 degrees; voltage should be steady between 0.5V and 4.5V depending on the angle.
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 associated with the steering wheel position sensor; look for frays, breaks, or corrosion.
- 22. Verify the sensor voltage during operation; should be between 0.5V and 4.5V. If not, check for power supply issues.
- 33. Test the sensor output while turning the steering wheel; ensure the voltage changes smoothly from 0.5V to 4.5V. If it’s erratic, replace the sensor.
- 44. Clear the code and test drive the vehicle to see if the code reappears.
Common causes
- Faulty steering wheel position sensor
- Wiring issues or damaged connectors
- Power loss in the sensor circuit

Frequently asked questions
Is it safe to drive with this code active?
It's moderate severity; you can drive, but steering and traction control may be compromised.
Will this code come back after clearing?
If there's a persistent issue with the sensor or wiring, yes, it will likely return.
Why does this affect traction control?
The system uses steering position data to adjust stability; a faulty sensor can confuse the control systems.
