P2D85 code meaning
Battery Charger B Input Current Sensor Circuit Range/Performance
What P2D85 means
P2D85 is for an input current reading of charger B that lies within the electrical limits yet cannot be true. No manufacturer documents P2D85 publicly. Its A-side model P0D39 shows the usual test, a check of the zero point while no current should flow: Mitsubishi sets it on the 2022 Outlander PHEV if at least 1.5 A shows up for 2 s while charging is not yet permitted by the PHEV control unit; GM's 2011 Volt module reacts once the offset hits 5.4 A in 512 out of 640 ms. CARB wants such rationality faults filed separately from circuit faults, and allows sensors mounted on a control unit's circuit board to share one code for circuit and range faults. A drifting sensor makes the charger misjudge its power. Hard low or high faults are P2D83 and P2D84.
P2D85 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 P2D85
- Charging refused or stopped soon after plugging in
- Charging power lower than expected
Common causes of P2D85
- Most likelyZero-point drift of the charger B current sensor
- PossibleReal residual current through a defective input stage while charging is not released
- Less likelyCalibration or software fault of the charger
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2D85 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 85 | The exact fault in that area. |
What to do next
- Note P2D85 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 P2D85
What does P2D85 mean?
P2D85 means "Battery Charger B Input Current Sensor Circuit Range/Performance". P2D85 is for an input current reading of charger B that lies within the electrical limits yet cannot be true. It is a generic code, so it means the same on every make.
Is it safe to drive with P2D85?
P2D85 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P2D85 fail an emissions test?
P2D85 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 P2D85 to fix?
Difficulty: workshop only. A typical repair takes 1 to 5 hours of work. This is a job for a workshop.
Will P2D85 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
