Steering Angle Sensor Invalid Data
The steering angle sensor is sending incorrect or unexpected data.
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 angle sensor is a device that tells the computer how much you are turning the steering wheel. If it's broken or giving wrong signals, the system doesn't know what you're doing, which affects things like stability control.
What the computer is actually seeing
The computer expects the steering angle sensor to report a specific voltage or angle when the wheel is turned. Values are usually around 0 to 5 volts, corresponding to -45 to +45 degrees. If the voltage fluctuates unexpectedly, or reads out of this range, it triggers the fault code.
What a healthy reading looks like
0-5 volts indicating steering position, typically 0 volts at 0 degrees (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.
- 1Check the wiring and connectors of the steering angle sensor for damage or corrosion. If you see any issues, fix them and clear the code before proceeding.
- 2Use a multimeter to check the voltage at the steering angle sensor. You should see a voltage between 0 and 5 volts as you turn the wheel. If the voltage is outside this range, replace the sensor.
- 3If the sensor checks out but the code returns, inspect the vehicle's alignment and steering mechanism. Make sure there are no binding components affecting the sensor reading.
Common causes
- Dirty or corroded connectors
- Faulty steering angle sensor
- Wiring damage or shorts

Frequently asked questions
Is it safe to drive with this code?
It's moderate; you can drive, but stability control might not work correctly. Fix it soon.
Will the code come back after clearing it?
If the issue isn't fixed, yes, it likely will come back.
Why does this code appear with C0810?
C0810 indicates a sensor failure; if both are present, it may point to a larger issue with the steering system.
