Steering Angle Sensor Calibration Fault

The steering angle sensor isn't calibrated properly or has an issue.

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 tells the car's computer how far and in which direction the steering wheel is turned. If it's off or broken, the car won't know how to control the steering properly.

What the computer is actually seeing

The computer sees inconsistent or abnormal data from the steering angle sensor, which should output a voltage between 0.5V and 4.5V depending on the steering wheel position.

What a healthy reading looks like

Steering angle sensor output should be between 0.5V to 4.5V, corresponding to -90° to +90° steering angle; if outside this range, a fault is detected.

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.

  1. 11. Check for any visible wiring damage or loose connectors at the steering angle sensor. Repair as necessary and retest.
  2. 22. Use a scan tool to check for related codes. If other codes are present, address them first before proceeding.
  3. 33. Inspect the steering angle sensor itself for damage. If physical damage is found, replace the sensor.
  4. 44. If the sensor appears okay, check the voltage signal from the sensor while turning the steering wheel. It should be between 0.5V and 4.5V. If not, replace the sensor.
  5. 55. After replacing, use a scan tool to calibrate the steering angle sensor according to manufacturer specifications.

Common causes

  • Faulty steering angle sensor
  • Wiring issues or loose connectors
  • Faulty steering column
  • Software/calibration error in the ECU
