Steering Angle Sensor Circuit Malfunction
The steering angle sensor signal is out of range or missing.
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 system is expecting to see a signal from the steering angle sensor that tells it how far and which direction the steering wheel is turned. If that signal isn't there or it doesn't make sense, the car needs to check what's wrong.
What the computer is actually seeing
The computer relies on the steering angle sensor to provide a voltage between 0.5V and 4.5V, depending on the position of the steering wheel. If the sensor doesn't send a signal or if it sends a faulty signal outside of this range, a C0622 code will trigger.
What a healthy reading looks like
Expected voltage range from the steering angle sensor is between 0.5V to 4.5V under normal operation.
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 the wiring and connectors for the steering angle sensor for damage or corrosion. Repair as necessary.
- 22. Use a multimeter to measure the voltage output from the steering angle sensor. Ensure it is within 0.5V to 4.5V while turning the wheel.
- 33. If the voltage is outside the expected range, replace the steering angle sensor and clear the code.
- 44. If the voltage is correct, check the vehicle's ground connections and repair if necessary.
- 55. Recalibrate the steering angle sensor using a scan tool, then recheck for codes.
Common causes
- Faulty steering angle sensor
- Damaged wiring or connectors
- Poor vehicle ground
- Calibration issue
- Electronic control unit (ECU) malfunction
