Steering Angle Sensor Invalid Data
The steering angle sensor is sending invalid data to the vehicle's computer.
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 measures how far you've turned the steering wheel, helping your vehicle know where it's headed. If it's broken or wired wrong, it'll send incorrect info to the computer, which can mess with traction control and stability functions.
What the computer is actually seeing
The vehicle's computer expects a variable voltage signal from the steering angle sensor, usually between 0.5 to 4.5 volts, depending on the position of the steering wheel. When it sees voltages outside this range or a constant voltage, it flags a fault.
What a healthy reading looks like
0.5 to 4.5 volts, varying based on steering input; typically, 2.5 volts should represent the wheel being centered.
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 connectors to the steering angle sensor for any signs of damage or corrosion.
- 22. Check the voltage at the steering angle sensor with the key on (engine off). Expect between 0.5 to 4.5 volts; a steady voltage indicates a problem.
- 33. If voltage is correct, check if the sensor is properly calibrated. Use a scan tool to perform calibration if necessary.
- 44. Clear the code and test drive the vehicle. If the code returns, replace the steering angle sensor.
Common causes
- Faulty steering angle sensor
- Wiring issues or damaged connectors
- Malfunctioning power steering system
- Calibration error after repairs

Frequently asked questions
Is it safe to drive with this code?
While you can still drive, it may affect traction control and stability, so fix it soon.
Will this code come back after clearing it?
Yes, if the underlying issue isn't fixed, the code will likely return.
Why does this code sometimes show up with ABS codes?
Both systems use the steering angle sensor, so issues with the sensor can trigger both types of codes.
