Steering Position Sensor Circuit Range/Performance Problem
The steering position sensor data is out of range or not performing correctly.
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 computer checks how much you're turning the steering wheel, and when it sees a value that's way off, it throws this code. This can happen if the sensor is bad or if there's a wiring issue.
What the computer is actually seeing
The steering angle sensor sends voltage signals to the computer. Normally, you should see a voltage range around 0.5 to 4.5 volts as you turn the wheel from lock to lock. If the voltage is outside this range or fluctuates wildly, the code sets.
What a healthy reading looks like
Expected voltage values should be between 0.5V (full left) and 4.5V (full right), with a linear response in between during turning.
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 connector to the steering position sensor for damage or corrosion. Repair as needed. Decision: If wiring looks good, proceed to step 2.
- 22. Use a multimeter to check the voltage output of the steering position sensor at various wheel positions. Expected value is 0.5V to 4.5V. Decision: If the sensor outputs are within range, suspect the steering control module; if not, replace the sensor.
- 33. If replacing the sensor, ensure to clear all codes and test drive the vehicle to see if the code returns. Decision: If the code does not reappear, the issue is resolved; if it does, inspect for further wiring problems.
Common causes
- Faulty steering position sensor
- Wiring issues (frayed, shorted, or open circuits)
- Corrosion in connectors
- Mechanical binding in the steering column or rack
- Faulty steering control module

Frequently asked questions
Is it safe to drive with this code active?
It's generally safe to drive, but you may experience reduced steering assist or handling issues, which can be dangerous in certain situations.
Will the code come back after I clear it?
If the underlying issue is not fixed, such as a faulty sensor or wiring problem, then yes, the code could return.
Why does this code appear with traction control light on?
The steering position sensor is critical for stability and traction control systems; an issue here can disable those aids, triggering warning lights.
