Steering Angle Sensor Fault
The steering angle sensor is reporting an issue with its signal or operation.
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 and in what direction you've turned the steering wheel. If it can't provide a correct reading, it can cause issues with safety features like traction control and stability systems.
What the computer is actually seeing
The computer monitors the steering angle sensor for expected voltage signals that range between 0.5V and 4.5V, representing turning left or right. Any deviations can trigger the fault code.
What a healthy reading looks like
Expected range is between 0.5V (full left) and 4.5V (full right) with 2.5V representing straight ahead position.
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.
- 1Check for obvious wiring damage or loose connections at the steering angle sensor; repair as needed.
- 2Using a scan tool, monitor the live data from the steering angle sensor. Verify voltage levels fall within expected values (0.5V to 4.5V).
- 3If the voltage readings are outside of the expected range, replace the steering angle sensor.
- 4If sensor readings are normal, inspect the CAN bus for faults that might interfere with communication.
Common causes
- Wiring issue between the sensor and the computer
- Faulty steering angle sensor
- Poor electrical connection at the sensor plug
- Physical damage to the sensor or its mounting

Frequently asked questions
Can I drive with this code present?
Yes, but be cautious as traction control and stability features may not work properly.
Will this code come back after clearing?
It may return if the underlying issue isn’t resolved.
Why does this code appear with U0415?
U0415 indicates invalid data from the steering angle sensor, which is directly related to the C1044 fault.
