Steering Angle Sensor Calibration
The steering angle sensor is not calibrated properly or has a fault.
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 turn the steering wheel. If it's off, the vehicle's stability control won't work right, and you might lose control in slippery conditions.
What the computer is actually seeing
The vehicle’s computer expects the steering angle reading to match the position of the steering wheel. If the readings differ significantly (more than ±5 degrees), it sets a fault code.
What a healthy reading looks like
The steering angle sensor should read approximately 0 degrees when the wheel is straight and correspond to actual steering input within ±5 degrees.
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 for the steering angle sensor. Look for frays, corrosion, or loose connections. If any issues are found, repair them. END.
- 22. Use a scan tool to check the current steering angle readings while manually moving the wheel. Ensure they reflect the actual position. If not, consider replacing the sensor. END.
- 33. If the sensor readings are correct, perform a calibration process using a scan tool or follow the manufacturer's procedure. After calibration, check for codes again. END.
- 44. If the code returns after calibration, inspect the stability control system and software for updates or faults. END.
Common causes
- Incorrect steering angle sensor calibration
- Faulty steering angle sensor
- Damaged wiring or connectors to the sensor
- Software issues in the ABS or stability control system

Frequently asked questions
Is it safe to drive with this code?
It's drivable, but the vehicle may not handle well in slippery conditions due to potential stability control failures.
Will this code come back after I clear it?
If the underlying issue is unresolved, such as a faulty sensor or wiring problem, the code is likely to return.
Why does this code pair with C1280?
C1280 indicates a steering angle sensor logic fault, which often occurs together with calibration errors like C1284.
