P0E3E Control Pilot Indicator Control Circuit High

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

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.

Likely causes

Indicator wire chafed against a supply wire near the charge port
Output stage in the module stuck on
Water in the charge port connector bridging pins

Symptoms

  • Pilot indicator lit or flickering without reason
  • Misleading charge port light while charging works
