Steering Angle Sensor Calibration Fault
The steering angle sensor is out of calibration or faulty.
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 the steering wheel is turned and sends that information to the computer. If there's a problem, it might think the wheel is turned when it's not, leading to issues like traction control problems.
What the computer is actually seeing
The computer sees an incorrect voltage output from the steering angle sensor, typically a lower or higher voltage than expected under predefined positions (usually around 0.5 to 4.5 volts).
What a healthy reading looks like
Typically 0.5 to 4.5 volts corresponding to the range of motion of the steering wheel.
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 of the steering angle sensor for signs of damage or corrosion. If damaged, repair or replace the wiring/connector.
- 22. Using a scan tool, check the live data from the steering angle sensor. Verify the voltage levels against expected values (0.5 to 4.5 volts). If out of range, proceed to the next step.
- 33. Check vehicle history and confirm if the sensor was recently replaced or the steering system serviced. If calibration was missed, recalibrate the sensor according to the manufacturer's procedures.
- 44. If still faulty, replace the steering angle sensor. Retest for codes after replacement.
Common causes
- Faulty steering angle sensor
- Wiring issues or damaged connectors
- Calibration not performed after repair or replacement of steering components
- Faulty ABS module affecting the sensor signals

Frequently asked questions
Is it safe to drive with this code?
It's moderate severity, so it’s best to fix it soon. You might experience traction control issues or affected handling.
Will the code come back after clearing it?
If the underlying issue isn't fixed, yes, it will return.
Why does this code pair with ABS codes?
Issues with the steering angle sensor can affect ABS operation since it uses the steering data to optimize brake performance.
