Steering Angle Sensor Circuit Malfunction
The steering angle sensor circuit has a failure.
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. If there's a problem, like a bad connection or a faulty sensor, the system won't know where the wheels are pointing, which can mess with things like stability control.
What the computer is actually seeing
The computer monitors the voltage from the steering angle sensor, expecting to see a range that corresponds to the wheel's position. A consistent voltage outside normal parameters, like 0.5V to 4.5V when the wheel is centered, triggers this code.
What a healthy reading looks like
Normal output voltage should be between 0.5V and 4.5V, depending on the steering position. If the sensor is centered, you should see 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 connectors for damage or corrosion. Fix any issues found.
- 22. Check the steering angle sensor output with a multimeter. Test for 0.5V to 4.5V as the wheel turns.
- 33. Remove and inspect the steering angle sensor. Look for physical damage or wear.
- 44. Replace the steering angle sensor if the output voltage is outside expected values or if it's damaged.
- 55. Clear the fault codes and conduct a test drive to see if the code reappears.
Common causes
- Faulty steering angle sensor
- Wiring issues
- Poor electrical connections
- Faulty steering column module
