Steering Position Sensor Circuit Range/Performance Problem
The steering position sensor is reporting values outside its normal 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 sensor is supposed to give the computer a specific voltage based on how much you turn the wheel. If it gives a voltage that's way too high or low, that's a problem.
What the computer is actually seeing
The steering position sensor sends a voltage signal that should range from about 0.5V to 4.5V based on the steering angle. If the signal is outside this range, the ECU will trigger the fault code.
What a healthy reading looks like
Voltage from steering position sensor should range from 0.5V (full right) to 4.5V (full left), typically around 2.5V at center.
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 connectors to the steering position sensor for damage or loose connections. Repair as needed and retest.
- 22. Measure the voltage output from the steering position sensor with a multimeter. It should be between 0.5V and 4.5V depending on the wheel position. If outside this range, go to step 3.
- 33. Use a scan tool to monitor the steering sensor values in real-time while turning the wheel. If no change is detected, replace the steering position sensor.
- 44. If the sensor voltage is within range, inspect the steering column electronics and ground connections. Repair as needed.
Common causes
- Faulty steering position sensor
- Wiring issue or connector damage
- Faulty steering column electronics
- Bad ground connection

Frequently asked questions
Is it safe to drive with this code?
Yes, but steering assist may be impaired, so drive cautiously and fix it soon.
Will this code come back after clearing?
If the underlying issue isn't resolved, it will likely return.
Why is this code triggered along with others?
Steering sensor issues can lead to multiple fault codes due to interrelated systems in steering response.
