P0E6F code meaning
Battery Charging System Precharge Contactor Control Circuit Low
What P0E6F means
P0E6F points to the coil control line of the charging precharge contactor sitting too low, most likely shorted to ground. With a high-side driver the coil then cannot be energised, so precharge never starts; the driver itself may shut down to protect itself. No manufacturer documents P0E6F publicly. GM notes for the comparable high-side monitor of its positive charging contactor (P0D0A, 2019 hybrid tables) that it cannot detect a short to ground at all, which is why a separate low code makes sense. Mitsubishi's i-MiEV stores P0AE6 when the coil feedback of its charging contactor stays off while the module commands it on; it names wiring, the contactor and the EV-ECU as causes. P0E70 is the high counterpart, P0E6D an open coil circuit.
P0E6F at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor1 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0E6F
- Charging does not start, contactor click missing
- High-voltage fault message when plugging in
Common causes of P0E6F
- Most likelyCoil control wire shorted to ground inside or near the battery
- PossibleShorted turns in the contactor coil
- Less likelyDriver stage switched off by its overcurrent protection
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0E6F means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 6F | The exact fault in that area. |
What to do next
- Note P0E6F and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0E6F
What does P0E6F mean?
P0E6F means "Battery Charging System Precharge Contactor Control Circuit Low". P0E6F points to the coil control line of the charging precharge contactor sitting too low, most likely shorted to ground. It is a generic code, so it means the same on every make.
Is it safe to drive with P0E6F?
P0E6F does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0E6F fail an emissions test?
P0E6F is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P0E6F to fix?
Difficulty: workshop only. A typical repair takes 1 to 4 hours of work. This is a job for a workshop.
Will P0E6F clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
