P2D83 code meaning
Battery Charger B Input Current Sensor Circuit Low
What P2D83 means
P2D83 says the current sensor at the input of charger B outputs a signal under its valid range. No manufacturer documents P2D83 publicly. For charger A the same fault is P0D3A, which Mitsubishi interprets on the 2022 Outlander PHEV as a ground short. Below 0.344 V of sensor output (roughly -54 A) for half a second, with 10-16 V on the charger, ends the charge, and the repair is a replacement charger/DC-DC assembly. In GM's 2011 Volt, the charger module treats an AC reading below 0.8 A in 160 out of 200 ms as Type A. Toyota's RAV4 Prime proves that a B stage has its own input current monitoring. The sensor usually sits inside the charger. Too high is P2D84, implausible values P2D85, the general circuit code P0E8A.
P2D83 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor1 to 5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2D83
- AC charging aborts shortly after starting
- Reduced charging power if only charger A is still used
Common causes of P2D83
- Most likelyCurrent sensor of charger B or its signal path shorted to ground inside the unit
- PossibleSensor supply inside the charger missing
- Less likelyDamaged internal connection or external harness where the sensor is separate
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2D83 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 83 | The exact fault in that area. |
What to do next
- Note P2D83 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 P2D83
What does P2D83 mean?
P2D83 means "Battery Charger B Input Current Sensor Circuit Low". P2D83 says the current sensor at the input of charger B outputs a signal under its valid range. It is a generic code, so it means the same on every make.
Is it safe to drive with P2D83?
P2D83 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P2D83 fail an emissions test?
P2D83 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 P2D83 to fix?
Difficulty: workshop only. A typical repair takes 1 to 5 hours of work. This is a job for a workshop.
Will P2D83 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
