P0E1F Hybrid/EV Battery Pack Coolant Pump A Control Circuit Driver Current/Temperature Too High

P0E1F reports that the output stage switching battery coolant pump A has hit its current or temperature limit. Ford uses the code on its 2020 hybrids. On the Escape HEV built up to 10 June 2020, bulletin 20-2221 lists P0E1F in the battery energy control module beside pump and battery codes and blames strategies in the BECM software, fixed by reprogramming PCM and BECM. Bulletins 20-2293 and 20-2345 name it for the Explorer, Police Interceptor Utility and Aviator hybrids, with the MIL on and a BECM update as the cure. If software is ruled out, the hardware logic applies: smart switches such as TI's automotive high-side parts shut off at their current limit or around 150 °C and report the event. A stiff pump, a short in the motor or a heat-soaked module remain. Pump B has the same code as P0E1E.

Likely causes

Battery energy control module software (Ford 2020 hybrids)
Pump A binding or seized and drawing excess current
Partial short in the pump motor or harness
Output driver overheating in the module

Symptoms

  • Check engine light on
  • Battery coolant pump stops intermittently
  • Hybrid power limited when the battery gets warm
