EV Charging Current Sensor Circuit Fault

The onboard charging control module has logged an erratic or completely absent voltage signal from the high-voltage direct-current charging sensor. Because the vehicle cannot accurately track how many amps are pouring into the battery pack, it halts charging to prevent overcharging cells.
