C0054 Steering Wheel Position Sensor Signal C

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modePossible

Covers signal C of the steering wheel position sensor, the third multi-track channel the ESC module uses with signals A, B and D to reconstruct absolute steering angle and detect a bad channel by cross-checking. This code is set when channel C is out of range, open, shorted or inconsistent with the others. Ford documents C0054 together with C0052, C0053 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, in which redundant tracks guard against a single wrong angle.

Likely causes

Signal C open or unconnected
Steering angle sensor channel C failed
Harness or connector fault

Symptoms

  • Stability control disabled
  • ABS/ESC warning lamp on
  • Implausible steering angle reading
