P0E8ABattery Charger B Input Current Sensor Circuit
- Generic OBD-II code · Powertrain
- How the car detects it
- P0E8A concerns the measurement, not the current itself: the sensor that tells charger B how much current enters at its input delivers no usable signal. It is the general circuit code; range, low and high faults of the same sensor sit at P2D85, P2D83 and P2D84, and the sensor of charger A uses P0D38. No manufacturer documents P0E8A publicly. That the B input current is evaluated is clear from P0E89, which Toyota sets on the RAV4 Prime as a circuit current above threshold and Ford tests against a 100 A limit. CARB requires inputs such as this to be checked for open circuits and out-of-range signals. In most chargers the sensor sits inside the unit, so a confirmed fault usually means repairing or replacing the charger. Without the reading, charging is refused or stopped.
