P061E Internal Control Module Brake Signal Performance

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modePossible

Electronic throttle systems run a second, independent calculation on the same processor (level 2, at Ford 'IPC – independent plausibility check') that recomputes driver demand, permitted and actual torque and their inputs, and compares them with the main software. Torque monitoring needs a reliable brake signal: brake applied means zero driver demand, cruise is cancelled, and in pedal limp mode the engine returns to idle. Ford introduced a brake switch with two outputs for this. P061E means the brake information is implausible inside the module – main software and monitoring do not see the same state, or the redundant brake data from the ABS module is invalid. Ford petrol engines set it within 1 s with the wrench lamp but no check engine light; from model year 2018 Ford replaced it with U1012. Ram 6.7 L Cummins (2019) fixed it by reprogramming. Brake switch circuit faults are P0571–P0573 and P0504.

Likely causes

Engine module software or calibration fault (update available)
Brake light switch misadjusted or faulty (both outputs do not switch together)
Faulty brake data from the ABS module or CAN disturbance
Connector or wiring fault at the brake switch
Internal defect of the engine module

Symptoms

  • Wrench lamp (Ford), no check engine light
  • Cruise control not working
  • Possibly reduced power
  • Stop-start possibly blocked
