P0D55 code meaning
Battery Charger Hybrid/EV Battery Output Current Sensor Circuit Intermittent/Erratic
What P0D55 means
P0D55 describes an output current signal from the charger that flickers, jumps or briefly drops out rather than tracking the regulated charging current. No manufacturer documents P0D55 publicly. GM and Mitsubishi publish only fixed limits (P0D53 and P0D54) and, at Mitsubishi, a zero-point test (P0D52) for this sensor; a sudden step that returns to normal would not necessarily trip those. CARB's charger requirement for plug-in hybrids is the regulatory basis for monitoring the signal at all. Typical triggers are intermittent internal contacts, solder fatigue from heat cycles during charging, or electrical noise from the charger's switching stage. The likely result is charging that stops and restarts or finishes much later than expected.
P0D55 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0D55
- Charging pauses and resumes repeatedly
- Charging takes much longer than usual
- Occasional charging system warning
Common causes of P0D55
- Most likelyIntermittent contact in the current measuring path of the charger
- PossibleSolder joints fatigued by charging heat cycles
- Less likelySwitching noise coupling into the sensor signal
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0D55 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 55 | The exact fault in that area. |
What to do next
- Note P0D55 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0D55
What does P0D55 mean?
P0D55 means "Battery Charger Hybrid/EV Battery Output Current Sensor Circuit Intermittent/Erratic". P0D55 describes an output current signal from the charger that flickers, jumps or briefly drops out rather than tracking the regulated charging current. It is a generic code, so it means the same on every make.
Is it safe to drive with P0D55?
P0D55 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0D55 fail an emissions test?
P0D55 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P0D55 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P0D55 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
