Steering Angle Sensor Signal Malfunction
The steering angle sensor has detected a malfunction in its signal.
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 tracks how far the steering wheel is turned; if it's sending bad data, the system won't know how to control things like traction or stability.
What the computer is actually seeing
The computer monitors the voltage output from the steering angle sensor, typically around 0.5 to 4.5 volts, based on steering input. If it drops below 0.5V or above 4.5V continuously, a fault code triggers.
What a healthy reading looks like
Steering angle sensor output should be between 0.5V to 4.5V depending on the angle. The sensor's reading must correlate with the actual position of the steering wheel.
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. Visually inspect the steering angle sensor wiring and connectors for damage or corrosion. Decision: If found, repair or replace.
- 22. Check the steering angle sensor output using a multimeter; should be between 0.5V and 4.5V. Decision: If readings are outside this range, replace the steering angle sensor.
- 33. Use a scan tool to view live data of the steering angle sensor; ensure it changes smoothly with steering input. Decision: If data is erratic, consider replacing the sensor; if smooth, investigate ECM calibration.
Common causes
- Faulty steering angle sensor
- Damaged wiring harness
- Poor connection at the sensor or ECM
- Calibration issues after a repair or component replacement

Frequently asked questions
Is it safe to drive with this code?
It's moderate severity; you can drive, but be cautious as traction control and stability may be compromised.
Will the code come back after clearing?
If the underlying issue isn't fixed, yes, it will likely reappear.
Why is this code linked with other codes?
Faulty sensors can affect multiple systems, hence causing related codes to trigger.
