P0D47Battery Charger 14 Volt Output Current Sensor Circuit
- Generic OBD-II code · Powertrain
- How the car detects it
- P0D47 is the general circuit code for the current sensor in the charger's 14 V output, the measurement of how much current the charger's internal low-voltage stage delivers. No manufacturer publishes this code; GM's Volt and ELR charger module measures the same current but reports only low and high readings (P0D49, P0D4A), with 54 A as its upper limit. Range and sporadic faults have the codes P0D48 and P0D4B. The Ford patent on a DC/DC stage housed in the charger describes such a unit feeding the 12 V bus whenever the car is connected to a charging station. Under CARB rules every input of this kind must be checked for circuit faults. Without a valid current value the charger cannot limit its auxiliary output, so it may switch that stage off.
