P0E67Battery Charger Control Circuit High
- Generic OBD-II code · Powertrain
- How the car detects it
- P0E67 is set when the charger command line reads higher than commanded, for instance close to battery voltage while the control unit is holding it off. A short to a live wire is the classic cause; with some driver designs an open line also floats high and lands here. The risk is the reverse of P0E66: depending on how the signal is defined, the charger may see a permanent request and try to start, or the module may stop charging as a precaution. No manufacturer documents P0E67 publicly. GM covers the line in the 2016 Volt (VICM) only with the general code P0E65, Type B, 30 of 40 samples at 25 ms. CARB expects a plug-in hybrid to detect charger malfunctions that disable or restrict charging, which applies here as well.
