P0E41Charge Status Indicator B Control Circuit Low
- Generic OBD-II code · Powertrain
- How the car detects it
- P0E41 refers to a second charge status light, indicator B, whose driver circuit is pulled too low, usually by a short to ground. Which light carries the letter B is the maker's choice; a lamp at the charge port alongside the dashboard light would be a typical pair. No manufacturer documents P0E41 publicly, and the GM Volt and ELR tables only cover indicator A. By analogy with GM's P0D2C test on light A (12OBDG01A), a ground short would be checked while the LED is commanded on, with 40 of 50 samples at 100 ms. Because indicator B usually sits in the exposed charge port area, a pinched harness or water ingress there deserve the first look. Indicator A keeps working if only B is affected. The open-circuit code for B is P0DE5, the high case P0E42.
