P0D48Battery Charger 14 Volt Output Current Sensor Circuit Range/Performance
- Generic OBD-II code · Powertrain
- How the car detects it
- P0D48 marks a current reading at the charger's 14 V output that lies within its electrical range but makes no sense in context. No manufacturer documents P0D48. GM covers a related check differently: its Volt and ELR charger module multiplies the 14 V output voltage by the current and sets P0D5B when this low-voltage power exceeds a limit derived from the measured AC input power plus 125 W. Out-of-range current faults are P0D49 and P0D4A, the circuit code is P0D47. CARB defines a rationality diagnostic as comparing a sensor with all other available information, which is exactly what this code represents. Suspects are drift in the charger's sense circuit or its software; repair normally means reprogramming or replacing the charger.
