P0E3EControl Pilot Indicator Control Circuit High
- Generic OBD-II code · Powertrain
- How the car detects it
- P0E3E is the high-side counterpart for the control pilot indicator circuit: the module senses voltage on the LED line when there should be little or none, the classic sign of a short to a supply wire. Publicly, no manufacturer documents P0E3E. On the Chevrolet Volt, GM's 2011 and 2012 tables still handle this under P0D2B, as a second case checked while the LED is commanded off, where 40 of 50 readings, one per 100 ms, have to fail. Shorts to voltage tend to come from chafed wiring at the charge port, where several feeds run side by side, or from a failed driver stage. The LED may glow permanently or flicker regardless of the real pilot state. P0E3D is the low case, P0D2B the open circuit; charging is normally not blocked.
