C0200 C0xxx · Chassis (C) High severity
Steering Angle Sensor / Transfer Case Range Fault
The steering angle signal is missing, out of range or not learned. Stability control and electric power steering assistance depend on it.
Severity guidance: High — stop driving and diagnose now; risk of further damage
Symptoms you will notice
- ESP lamp on
- Steering assist inconsistent
- Lane-keeping and ADAS functions disabled
- Vehicle pulls assistance strategy into default
Common causes
Ordered from most to least likely — start at the top.
- 1 Steering angle sensor not calibrated
- 2 Clock spring failure
- 3 CAN data fault from the sensor
- 4 Steering work without recalibration
How to diagnose it
Cheapest and least invasive first — most of these codes are not a parts problem.
- ✓ Check whether the steering or suspension was recently worked on — recalibration is then the likely fix.
- ✓ Read live steering angle and turn lock-to-lock to check the sweep.
- ✓ Perform the manufacturer's zero-point calibration.
- ✓ Inspect the clock spring if the signal drops intermittently.
Repair options
- Perform steering angle sensor calibration
- Replace the clock spring
- Repair the CAN wiring
C0200 — frequently asked questions
Why does it appear after a wheel alignment? +
The sensor's zero point no longer matches straight-ahead. Recalibrate after any steering or alignment work.
Does ADAS stop working too? +
Yes — lane-keeping and camera-based functions rely on a valid steering angle signal.
