P0D54Battery Charger Hybrid/EV Battery Output Current Sensor Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Needs a drive cycle to confirm a fix
- How the car detects it
- P0D54 marks a current reading at the charger's high-voltage output that exceeds the sensor's upper limit. The limit sits well above normal charging current, so the value counts as an electrical fault rather than real current. GM's 2011 Volt charger module triggers at 18 A or more, the 2014 Volt/ELR table at 17.7 A, each over 400 of 500 ms and rated Type A with MIL. Mitsubishi's 2022 Outlander PHEV logs it as a short to supply once the sensor voltage exceeds 4.658 V, corresponding to roughly 54 A, for 0.5 s; charging is stopped and the charger/DC-DC unit replaced. While P0D54 is stored, GM suspends its output power plausibility test P0D5C. The low-side fault is P0D53.
- What you may notice

- Charge level stays unchanged after plugging in
- Likely causes
- LikelyCurrent sensor output shorted to supply voltage in the charger
- LikelyCharger current measuring stage failed
- RareSensor output stuck at its upper end
