Code P1ED6 Description

The diagnostic trouble code (DTC) P1ED6 indicates an issue with the battery charger cold plate temperature sensor circuit in the vehicle. This sensor is responsible for monitoring the temperature of the cold plate in the battery charger system, which is crucial for maintaining the optimal performance and efficiency of the battery charging process. When the voltage detected by the sensor is lower than the specified range, the code is triggered, indicating a problem with the sensor circuit.
