Steering Angle Sensor Signal Not Plausible
What does C0222 mean?
The C0222 code means the vehicle's onboard diagnostic system has detected: Steering Angle Sensor Signal Not Plausible. This is a critical severity code.
Common Symptoms
- Stability control disabled
- Traction control light on
- ESC intervenes at wrong times
- Service StabiliTrak or ESC message
- Multiple safety system warnings
Probable Causes (Ranked by Likelihood)
- Steering angle sensor reading does not match actual wheel direction Very High
- Sensor not recalibrated after steering work High
- Worn tie rod end or steering linkage causing play Moderate
- Steering column universal joint wear Moderate
- Internal sensor failure producing incorrect output Low
Step-by-Step Diagnostic Procedure
-
Compare steering angle sensor output to actual wheel position
-
Perform steering angle sensor calibration procedure
-
Check all steering linkage components for wear or looseness
-
Inspect the steering column for play in joints
-
Verify front wheel alignment is within specification
Frequently Asked Questions
What does not plausible mean?
It means the stability control module compared the steering angle sensor data with other sensor inputs like wheel speeds and yaw rate, and the steering data does not make sense. The vehicle may be turning right but the sensor says the wheel is straight.
Can worn steering components cause this code?
Yes. Excessive play in tie rod ends, ball joints, or the steering rack can cause the actual wheel direction to differ from what the steering angle sensor reports, triggering a plausibility error.
Will an alignment shop calibrate the sensor?
Reputable alignment shops with modern equipment will calibrate the steering angle sensor as part of the alignment. However, not all shops do this automatically. Ask specifically for sensor calibration after alignment work.
