P0E3D code meaning
Control Pilot Indicator Control Circuit Low
What P0E3D means
P0E3D concerns the lamp or LED that shows the state of the pilot connection to the charging station, not the pilot signal itself. Low means the driver circuit reads too little voltage, typically because the line to the LED is shorted to ground. No manufacturer documents P0E3D publicly. GM's Volt tables for 2011 and 2012 (11OBDG01, 12OBDG01A) fold this case into the older open-circuit code P0D2B: a ground short is detected while the LED is commanded on, with 12 failed samples out of 15 at one sample every 100 ms, Type B. The current code set gives the ground short its own code, while P0E3E takes the short to voltage. The indicator stays dark or wrong, charging normally continues. Pilot line faults are P0CF3 and P0CF4.
P0E3D at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0E3D
- Pilot indicator stays dark when it should light
- Charging itself usually unaffected
Common causes of P0E3D
- Most likelyWire to the indicator LED shorted to ground at the charge port
- PossibleShorted LED or indicator unit
- Less likelyFaulty output driver in the controlling module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0E3D means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 3D | The exact fault in that area. |
What to do next
- Note P0E3D 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 P0E3D
What does P0E3D mean?
P0E3D means "Control Pilot Indicator Control Circuit Low". P0E3D concerns the lamp or LED that shows the state of the pilot connection to the charging station, not the pilot signal itself. It is a generic code, so it means the same on every make.
Is it safe to drive with P0E3D?
P0E3D does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0E3D fail an emissions test?
P0E3D 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 P0E3D to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. This is a job for a workshop.
Will P0E3D clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
