P0E6D code meaning
Battery Charging System Precharge Contactor Control Circuit/Open
What P0E6D means
P0E6D concerns the low-voltage side of the charging precharge contactor: the coil circuit through which the control unit switches it, typically interrupted. Unlike P0E6C, which judges what happens on the high-voltage side, this code comes from the driver output itself. No manufacturer documents P0E6D publicly. GM uses the same method on the positive charging contactor of its 2019 hybrids (P0D0A): an open is recognised when the switched-off output still shows more than 4 V, or when less than 194 mA flows with the output on; 40 failed samples out of 50 at 12.5 ms set a Type B code. Mitsubishi's i-MiEV compares a coil monitor with the command and stores P0AE6 for the charging contactor. Range, low and high faults of the coil circuit are P0E6E to P0E70.
P0E6D 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 P0E6D
- Charging cannot be started
- High-voltage system fault message
Common causes of P0E6D
- Most likelyBroken coil control wire or unplugged connector
- PossibleOpen winding in the contactor coil
- Less likelyFailed driver stage in the battery management unit
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0E6D means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 6D | The exact fault in that area. |
What to do next
- Note P0E6D 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 P0E6D
What does P0E6D mean?
P0E6D means "Battery Charging System Precharge Contactor Control Circuit/Open". P0E6D concerns the low-voltage side of the charging precharge contactor: the coil circuit through which the control unit switches it, typically interrupted. It is a generic code, so it means the same on every make.
Is it safe to drive with P0E6D?
P0E6D does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0E6D fail an emissions test?
P0E6D 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 P0E6D to fix?
Difficulty: workshop only. A typical repair takes 1 to 4 hours of work. This is a job for a workshop.
Will P0E6D clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
