Steering Angle Sensor Range/Performance Problem
The steering angle sensor is reporting values out of the expected range.
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 so the computer can adjust the vehicle's systems accordingly. If this sensor fails or sends incorrect signals, the vehicle’s stability control might not work right, which can be dangerous.
What the computer is actually seeing
The computer expects the steering angle sensor to report a range of values corresponding to the steering wheel position, typically from -30° to +30°. If the readings exceed this range, like showing -40° or +40°, an error code will be triggered.
What a healthy reading looks like
Normal operation should have the steering angle sensor output between -30° to +30° during turns.
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 at the steering angle sensor for damage or corrosion. Check for loose connections.
- 22. Measure the voltage at the sensor while turning the steering wheel. You should see a smooth change in voltage, typically between 0.5V to 4.5V, as you turn from lock to lock.
- 33. If the range is correct but the code persists, recalibrate the steering angle sensor using a scan tool; check the manufacturer's instructions.
- 44. If the sensor still reports inaccurate values after recalibration, consider replacing the sensor.
Common causes
- Faulty steering angle sensor
- Wiring issues or poor connections
- Incorrect calibration of the sensor
- Alignment problems in the steering system
