GMW - Steering Wheel Position Sensor Range/Performance Problem
The steering wheel position sensor is out of range or has performance issues.
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 system measures the angle of the steering wheel, but the readings are off. If it says the wheel is at 45 degrees when it's actually straight, that's a problem.
What the computer is actually seeing
The powertrain control module (PCM) is receiving a signal from the steering wheel position sensor indicating an invalid position, such as a value outside the expected range of -180 to +180 degrees.
What a healthy reading looks like
Valid angles should be within -180 to +180 degrees. The sensor typically outputs a voltage between 0.5V (full left) to 4.5V (full right).
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. Check the wiring and connector at the steering wheel position sensor for damage or corrosion. Repair if necessary. Decision: If wiring/connector issues found, fix them. If not, go to step 2.
- 22. Using a scan tool, check the live data for the steering wheel position sensor. Look for values outside the -180 to +180 degree range. Decision: If values are out of range, go to step 3. If in range, consider replacing the sensor or software update.
- 33. Test the steering wheel position sensor with a multimeter. Check for voltage output while turning the wheel. Expected output is between 0.5V and 4.5V. Decision: If output is out of range, replace the sensor. If within range, further diagnose the steering column control module.
Common causes
- Faulty steering wheel position sensor
- Wiring issues or damaged connector
- Failed steering column control module
- Software calibration error

Frequently asked questions
Can I still drive with this code?
Yes, but you should fix it soon as it can affect steering responsiveness.
Will this code come back after clearing it?
If the underlying issue is not fixed, the code will likely return.
Why does this code sometimes pair with other codes?
Many steering-related faults can stem from common wiring or connector issues affecting multiple sensors.
