Steering Wheel Position Sensor Signal Range/Performance Problem
There's a problem with the steering wheel position 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 wheel position sensor tells the computer where the wheel is pointing. If it's out of range or not sending the right signal, the computer can't keep track and may think there's a steering issue when there isn't.
What the computer is actually seeing
The computer expects a voltage signal from the steering wheel position sensor that varies between 0.5V to 4.5V depending on the angle of the wheel. If it sees a signal outside this range, it triggers the fault code.
What a healthy reading looks like
Expected steering angle sensor voltage should be 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. Inspect the wiring and connectors to the steering wheel position sensor for damage, corrosion, or loose connections.
- 2--> If damaged, repair/replace the wiring or connectors. If good, proceed to step 2.
- 32. Use a scan tool to check the live data for the steering wheel position sensor voltage while manually turning the wheel.
- 4--> If the voltage is within the expected range (0.5V to 4.5V), the issue may be in the control module. If it's out of range, proceed to step 3.
- 53. Disconnect the steering wheel position sensor and test its resistance with a multimeter according to manufacturer specifications.
- 6--> If the sensor fails testing, replace it. If it passes, the control module may need reprogramming or replacement.
Common causes
- Faulty steering wheel position sensor
- Damaged wiring or connectors to the sensor
- Calibration issue after steering component replacement
- Software glitch in the power steering control module

Frequently asked questions
Is it safe to drive with this code?
It's drivable but steer with caution; there may be a lack of power steering assist.
Will this fault code come back after repairs?
If repairs are done correctly, it shouldn't come back. Always verify with a scan tool after repairs.
Why does this code pair with other codes?
Multiple codes can surface if the steering system has a broader issue, often related to the same sensors or circuits.
