P0C27Electric/Auxiliary Transmission Fluid Pump A Motor Current Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P0C27 means motor A of the auxiliary transmission fluid pump draws less current than expected, a sign that the pump is not loaded, for example because it sucks air or turns without delivering. Ford documents it twice. TSB 16-0111 covers 2014-16 Fusion and 2015-16 Edge with the 6F35 transmission and start-stop: MIL, P0C27 in the PCM and a harsh engagement after an auto-stop, caused by air entering the pump supply tube on transmissions built up to 26 February 2016; a new tube with a check ball fixes it. TSB 18-2282 for the 2013-17 Fusion Energi and C-Max Energi lists P0C27 and/or P0C28 and calls for reprogramming the PCM and hybrid module. P0C28 is the high side, P0C26 the general code, P0C2A a stalled motor.
- What you may notice
- MIL on
- Harsh transmission engagement after a start-stop event
- Likely causes
- LikelyAir entering the pump supply tube (Ford 6F35, new tube with check ball)
- PossibleCalibration of PCM and hybrid module (Ford Fusion/C-Max Energi)
- PossibleLow transmission fluid level letting the pump draw air
- RareHigh resistance or open circuit in the pump motor wiring
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
