P2E86Battery Charger B Input Voltage Sensor Circuit High

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.
