DTC codes / P2Exx · Hybrid propulsion / P2E86
P2E86 indicates that the powertrain control module has detected an abnormally high voltage on the input voltage sensor circuit for the battery charger, which is typically part of a hybrid or electric vehicle's charging system. The sensor monitors the voltage feeding the charger, and a high reading suggests a short to voltage, an open ground, or a sensor signal that exceeds the expected range.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
