P0E6EBattery Charging System Precharge Contactor Control Circuit Range/Performance
- Generic OBD-II code · Powertrain
- How the car detects it
- P0E6E is stored when the coil circuit of the charging precharge contactor neither shows a clean short nor an open, but its electrical behaviour does not match the command: coil current outside the expected window, a slow pull-in, or feedback that lags behind the switching command. Rising contact resistance in the connector, a coil with changed resistance or a weak supply to the driver are typical. No manufacturer documents P0E6E publicly. Related GM monitoring in the 2019 hybrid tables shows the measured quantity, a current sense feedback of the contactor driver with a 194 mA minimum while on, used there for the positive charging contactor (P0D0A). CARB requires output components to be checked for proper function, not only for circuit faults. Hard faults on the same circuit are P0E6D, P0E6F and P0E70.
- What you may notice
- Charging starts only on some attempts
- Fault appears mostly in cold weather or with a weak 12 V battery
- Likely causes
- PossibleIncreased contact resistance in the coil connector
- PossibleContactor coil resistance out of specification
- RareLow supply voltage at the contactor driver
