P0E86Battery Charger B Input Voltage Too Low
- Generic OBD-II code · Powertrain
- How the car detects it
- P0E86 means charger B sees less voltage at its input than it needs to work, although charging has been requested. It mirrors P0D27, which carries no letter and is used for the first charger. No manufacturer documents P0E86 publicly. Ford's plug-in hybrid summary (OBDSM1901) does list the opposite case on the same input, P0E87, which shows that the B input codes are in real use. A low input voltage is often caused outside the car: a weak or long house circuit, a faulty extension or charging cable, or a charging station that sags under load. Inside the car, worn inlet contacts or a bad high-voltage connection to the charger can do the same. CARB does not require faults originating in the supply to be detected, so an unconfirmed code may just reflect a poor socket.
- What you may notice

- PossibleWorn or burnt contacts in the charge inlet or its wiring to the charger
- RareVoltage measurement inside charger B reads too low
