Steering Angle Sensor Calibration Fault
The steering angle sensor calibration is out of range or faulty.
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 car's computer uses a sensor to know how much you've turned the steering wheel. If this sensor isn't calibrated correctly or is broken, the computer won't get the right information about your steering position.
What the computer is actually seeing
The steering angle sensor sends voltage signals (usually between 0.5 and 4.5 volts) based on its position. If the signal is outside expected parameters, the code C0476 will trigger.
What a healthy reading looks like
The sensor should output a voltage between 0.5V (minimum left turn) and 4.5V (maximum right turn) when the steering wheel is turned. At rest, it should be around 2.5V.
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 connector for the steering angle sensor for damage or corrosion. Repair as necessary.
- 22. Check the steering angle sensor output using a scan tool. Ensure the voltage is within 0.5V to 4.5V range while turning the steering wheel.
- 33. If the voltage is out of range, replace the steering angle sensor and calibrate it using a scan tool.
- 44. If the sensor is outputting correctly, check for other related fault codes that might indicate a broader problem with the vehicle’s steering system.
Common causes
- Faulty steering angle sensor
- Poor electrical connections or wiring issues
- Calibration issues after repair or service
