P2D67 code meaning
Battery Charging System Negative Contactor C Control Circuit Low
What P2D67 means
P2D67 is stored when the drive line of minus charging contactor C sits lower than the module expects, typically because the wire touches ground or the connector has taken in water. No manufacturer documents P2D67 publicly. A separate low check is needed because the usual open-load test misses this fault: GM states in its 2011 Volt table for the minus charge contactor (P0D11) that the test cannot detect a short to ground. CARB, on the other hand, allows opens and shorts on outputs to share one code, so certain systems log this case under P2D65. The effect of the short depends on which coil end is switched: contactor C may remain open, or the output stage protects itself by cutting out. P2D68 is the high case, P2D60 the plus side.
P2D67 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor1 to 5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2D67
- Charging mode via contactor C refused
- Fault more frequent after rain or washing
- Charging warning in the cluster
Common causes of P2D67
- Most likelyDrive wire chafed against the battery housing or body
- PossibleMoisture or corrosion in the contactor connector
- Less likelyShorted turns in the coil of minus contactor C
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2D67 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 67 | The exact fault in that area. |
What to do next
- Note P2D67 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 P2D67
What does P2D67 mean?
P2D67 means "Battery Charging System Negative Contactor C Control Circuit Low". P2D67 is stored when the drive line of minus charging contactor C sits lower than the module expects, typically because the wire touches ground or the connector has taken in water. It is a generic code, so it means the same on every make.
Is it safe to drive with P2D67?
P2D67 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P2D67 fail an emissions test?
P2D67 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 P2D67 to fix?
Difficulty: workshop only. A typical repair takes 1 to 5 hours of work. This is a job for a workshop.
Will P2D67 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
