P2E86Battery Charger B Input Voltage Sensor Circuit High
- Generic OBD-II code · Powertrain
- How the car detects it
- P2E86 flags an input voltage signal of charger B above the highest value the measurement can plausibly produce. Home sockets and AC stations stay far below that, so the fault normally lies in the sensing path or its signal line, rarely in the grid. No manufacturer documents P2E86 publicly. The charger A versions give the scale: GM's 2011 Volt treats an AC peak above 422 V for 160 of 200 ms as sensor high (Type A, MIL), and Mitsubishi's Outlander PHEV sets P0D40 when the sensor output passes 3.161 V, equal to more than 492 V, for 0.5 s, then halts charging and names the charger/DC-DC unit as the part to replace. CARB wants hybrid monitoring plans to cover charging system performance. Too low is P2E85, plausibility P2E84. AC charging usually stays blocked.
