Steering Angle Sensor Fault
Indicates a problem with the steering angle sensor's signal.
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 the position of the steering wheel and sends that data to the vehicle's computer. If it fails, the car can't accurately understand how the steering is being used, which can cause issues with stability control.
What the computer is actually seeing
The computer expects a steady voltage signal (typically between 0.5V and 4.5V) that varies as the steering wheel turns, indicating the angle and direction. If it detects a signal out of range or no signal at all, the code sets.
What a healthy reading looks like
Expected voltage should vary from 0.5V (full left) to 4.5V (full right) under a steady steering wheel turn.
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. Check for other stored codes that may indicate related issues. If other codes are present, address those first.
- 22. Inspect the wiring and connectors at the steering angle sensor for damage or corrosion. Repair or replace as needed, then retest.
- 33. Using a multimeter, check the voltage output of the steering angle sensor while turning the steering wheel. Verify that the voltage changes smoothly between 0.5V and 4.5V.
- 44. If the voltage is incorrect, replace the steering angle sensor and recalibrate the system according to the manufacturer's specifications.
- 55. If the sensor signals are correct but the code persists, check the vehicle stability control module and its connections.
Common causes
- Faulty steering angle sensor
- Loose or damaged wiring harness
- Bad connectors
- Calibration issues after alignment
- Faulty vehicle stability control module
