P0E87Battery Charger B Input Voltage Too High
- Generic OBD-II code · Powertrain
- How the car detects it
- P0E87 flags an input voltage for charger B above what the charger accepts. Ford uses the code in its plug-in hybrid OBD summary (OBDSM1901) in an unusual way: it is part of a plausibility test run on the battery controller (BECM) and judges the charging voltage request that reaches the charger. Once the charger is in its ready state, a requested value above 450 V counts as a fault, and the check needs less than one second. In that reading the code points to a wrong command over the network rather than to the grid, so module software and data on the bus deserve attention first. On other designs a measured overvoltage at the input would set it. Ford lets charger faults request the amber wrench lamp instead of a specific charging message. The low case is P0E86.
