P0E6E code meaning
Battery Charging System Precharge Contactor Control Circuit Range/Performance
What P0E6E means
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.
P0E6E 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 P0E6E
- Charging starts only on some attempts
- Fault appears mostly in cold weather or with a weak 12 V battery
Common causes of P0E6E
- PossibleIncreased contact resistance in the coil connector
- PossibleContactor coil resistance out of specification
- Less likelyLow supply voltage at the contactor driver
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0E6E means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 6E | The exact fault in that area. |
What to do next
- Note P0E6E 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 P0E6E
What does P0E6E mean?
P0E6E means "Battery Charging System Precharge Contactor Control Circuit Range/Performance". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P0E6E?
P0E6E does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0E6E fail an emissions test?
P0E6E 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 P0E6E to fix?
Difficulty: workshop only. A typical repair takes 1 to 4 hours of work. This is a job for a workshop.
Will P0E6E clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
