P0D07 code meaning
Battery Charging System Positive Contactor A Circuit
What P0D07 means
P0D07 is the general circuit code for positive contactor A of the charging system, the switch that joins the plus side of a charging path to the traction battery. Depending on the design this path comes from the DC fast-charge inlet or from the on-board charger; the Chevrolet Volt, for instance, places charging contactors between charger and pack. The code stands for an electrical fault in that contactor branch which fits no more specific case. No manufacturer documents P0D07 publicly; a GM patent describes judging such contactors by their coil current, and CARB requires plug-in vehicles to monitor charging components. Welded or non-closing contacts are P0D08/P0D09, driver faults P0D0A–P0D0D, the main pack contactors P0AA0 ff. Usually charging is blocked while driving still works.
P0D07 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor1 to 6 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0D07
- Charging not possible or aborted
- Charging system warning in the instrument cluster
Common causes of P0D07
- PossibleContactor coil open or shorted
- PossibleDamaged wiring or corroded connector in the contactor branch
- Less likelyFault in the module that drives and monitors the contactor
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0D07 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 07 | The exact fault in that area. |
What to do next
- Note P0D07 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 P0D07
What does P0D07 mean?
P0D07 means "Battery Charging System Positive Contactor A Circuit". P0D07 is the general circuit code for positive contactor A of the charging system, the switch that joins the plus side of a charging path to the traction battery. It is a generic code, so it means the same on every make.
Is it safe to drive with P0D07?
P0D07 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0D07 fail an emissions test?
P0D07 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 P0D07 to fix?
Difficulty: workshop only. A typical repair takes 1 to 6 hours of work. This is a job for a workshop.
Will P0D07 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
