P0E3F Charge Status Indicator A Control Circuit Low
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.
Likely causes
Symptoms
- Charge status light stays off during charging
- Charging continues normally
Repair estimate
