P0E3F code meaning
Charge Status Indicator A Control Circuit Low
What P0E3F means
P0E3F reports that the output feeding charge status indicator A sits too low in voltage. That light confirms to the owner that the vehicle is charging, and the expected cause is an LED line touching ground. No manufacturer documents P0E3F publicly. GM's Chevrolet Volt tables for 2012 (12OBDG01A) still count this situation under P0D2C: the ground short is looked for while the LED is commanded on, and 40 failing samples out of 50, one every 100 ms, confirm it as Type B. Newer code sets split it off as P0E3F, with P0E40 for the short to voltage and P0D2C left for the open circuit. The charge status light stays dark, so the owner cannot tell at a glance whether charging has started, though the charger itself keeps working.
P0E3F 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 P0E3F
- Charge status light stays off during charging
- Charging continues normally
Common causes of P0E3F
- Most likelyLED supply wire pinched or chafed to ground
- PossibleCharge status LED shorted internally
- Less likelyFailed 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 P0E3F means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 3F | The exact fault in that area. |
What to do next
- Note P0E3F 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 P0E3F
What does P0E3F mean?
P0E3F means "Charge Status Indicator A Control Circuit Low". P0E3F reports that the output feeding charge status indicator A sits too low in voltage. It is a generic code, so it means the same on every make.
Is it safe to drive with P0E3F?
P0E3F does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0E3F fail an emissions test?
P0E3F 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 P0E3F to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. This is a job for a workshop.
Will P0E3F clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
