C0052 Steering Wheel Position Sensor Signal A
Covers signal A of the steering wheel position sensor. Multi-track steering-angle sensors output several phase-shifted signals (A, B, C, D) so the ESC module can reconstruct absolute angle and detect a single bad channel by cross-checking. This code is set when channel A is out of range, open, shorted or does not agree with the other channels. Ford documents C0052 together with C0053, C0054 and C0055 on 2020-2021 Police Interceptor Utility vehicles, where the codes store in the steering module if the police-package steering-wheel accessory outputs are left unwired. A fault disables stability control and sets the ABS/ESC warning lamp while base braking remains. The entry follows the SAE J2012 generic definition and multi-track steering-angle sensor design.
Likely causes
Symptoms
- Stability control disabled
- ABS/ESC warning lamp on
- Implausible steering angle reading
Repair estimate
Typical range across vehicles; the real cost depends on what the testing finds.
