P2E4EBattery Charger Coupler Temperature C Too High
- Generic OBD-II code · Powertrain
- How the car detects it
- P2E4E is no sensor fault: measuring point C works, but the contact it watches has become too hot, so charging is cut back or ended. For orientation, a DOE laboratory report from August 2025 compares the IEC 62196-1 ceiling, 90 °C when the air is at 40 °C, with the fixed 100 °C of SAE J3400. No manufacturer documents P2E4E publicly. Others show the same logic under their own codes: Porsche stops Taycan charging when the NTC of the left or right charging inlet stays at 90 °C or above for more than 14 s (P31D200), and Hyundai addresses P1BAD on the 2022-2023 Ioniq 5 with a charge-management software update. Honda's Fit EV bulletin names a poor contact to the station plug as the heat source and lets the car finish at lower current. Heat from worn pins, dirt or a weak cable is typical. Sensor C circuit faults are P2E4A to P2E4D.
- What you may notice
- Charging slows down or stops partway through
- Charge indicator at the inlet flashes a fault or reduced-power state
- Discoloured or heat-marked pins at the plug or inlet
- Likely causes
- LikelyWorn, widened or dirty pins in the station plug or the vehicle inlet
- PossibleCharging cable with thin conductors heating up at high current (Porsche)
- PossibleLong high-current session in strong heat or direct sun
- RareTemperature logic in the charging software, update available
