Steering Position Sensor Circuit Range/Performance Problem
This code indicates an issue with the steering position sensor's output reading.
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 position sensor measures the angle of the steering wheel. If it sends readings outside its expected range, the system triggers this code.
What the computer is actually seeing
The steering position sensor sends a voltage signal that indicates the steering wheel angle. The expected voltage range is typically between 0.5V at full left and 4.5V at full right, with 2.5V representing center position. If these readings exceed the defined limits, the fault triggers.
What a healthy reading looks like
Voltage from the steering position sensor should be between 0.5V and 4.5V during normal operation.
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 steering position sensor wiring and connectors for damage or corrosion. Fix any issues found. Check for bent pins in the connectors.
- 22. Measure the voltage output of the steering position sensor with a multimeter. It should be between 0.5V and 4.5V depending on steering angle. If not, replace the sensor.
- 33. Check for mechanical binding in the steering system or damaged components. Ensure the steering moves freely without obstruction before further diagnosis.
- 44. Clear the code and perform a test drive. If it returns, diagnose the ECU for any software updates or compatibility issues.
Common causes
- Wiring issue or connector fault in the steering position sensor circuit
- Faulty steering position sensor
- Steering system mechanical blockage or damage
- ECU software error

Frequently asked questions
Is it safe to drive with this code?
It's not recommended to drive extensively as this can affect steering performance and safety.
Will this code come back after clearing it?
If the underlying issue isn't fixed, the code will likely return shortly after clearing.
Why does this code pair with other C0xxx codes?
Codes in the C0xxx range often indicate a fault within vehicle control systems, which can be interrelated, especially in stability or steering systems.
