What P0D22 means
P0D22 means the on-board charger does not deliver the high-voltage current it was asked for. GM's Volt compares actual and desired current in constant-current mode against a table: 150 of 300 samples set it in 2011, One Trip Type A; from 2014 a second part also catches a charger that was switched on, with more than 201 V commanded, but never enabled its output after 6 s. Mitsubishi's Outlander PHEV stops charging when target and actual differ by 3 A or more for 3 s. GM bulletins cite P0D22 with MIL and no charge on the 2011 and 2013 Volt (HPCM2 updates) and, in PIP6048, on the Lyriq, Optiq, Blazer EV and Equinox EV during level 2 charging, where reprogramming the BECM comes first. Voltage deviations belong to P0D20/P0D21, a shorted output to P0D23.
P0D22 at a glance
- Check engine lightYes, usually on
- 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 P0D22
- Vehicle does not charge or charging stops
- MIL on after a charge session ends
- Problem shows mainly on AC level 2 stations
Common causes of P0D22
- Most likelyCharge control software in the hybrid or battery control module (GM PIP bulletins)
- PossibleInternal fault in the on-board charger
- Less likelyFaulty output current measurement
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0D22 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 22 | The exact fault in that area. |
What to do next
- Note P0D22 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 P0D22
What does P0D22 mean?
P0D22 means "Battery Charger A Output Current Performance". P0D22 means the on-board charger does not deliver the high-voltage current it was asked for. It is a generic code, so it means the same on every make.
Is it safe to drive with P0D22?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P0D22 fail an emissions test?
P0D22 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 P0D22 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P0D22 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
