Mechanical System Failure - Steering Position Sensor
There is a fault in the steering position sensor or its circuit.
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 vehicle's computer is not getting the correct signal from the steering position sensor, which tells it where the steering wheel is positioned. This can cause issues with power steering and stability control systems.
What the computer is actually seeing
The computer expects to see a voltage signal from the steering position sensor within a range of 0.5V to 4.5V, depending on the steering angle.
What a healthy reading looks like
Expected voltage from the steering position sensor 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 wiring and connectors for damage or corrosion; repair as needed. Decision point: if wiring/connector issues found, fix them. If none, proceed to step 2.
- 22. Test the steering position sensor with a multimeter; check for proper voltage output while turning the wheel. Decision point: if voltage is outside 0.5V - 4.5V, replace the sensor. If voltage is good, proceed to step 3.
- 33. Check for mechanical obstruction or damage in the steering column/rack; verify the steering can move freely. Decision point: if obstructions found, clear them. If steering system is functional, further diagnosis may be needed.
Common causes
- Wiring issues (broken or shorted wires)
- Faulty steering position sensor
- Corroded or loose connectors
- Steering rack or column damage
Typical repair cost

Is it safe to drive with this code?
Moderate severity means you can drive it, but addressing the problem soon is crucial for steering stability.
Will this issue come back after clearing the code?
It can return if the underlying problem isn't fixed, especially if it’s wiring or connector-related.
Why do other codes appear with this one?
Related codes often point to the same issue or a cascade effect from the steering system failure.
