What P0D27 means
P0D27 says the AC voltage reaching the on-board charger sits lower than the charger accepts while charging is permitted. Unlike most charger codes, the cause often lies outside the car. Mitsubishi's Outlander PHEV stops charging and tells technicians to check, in order, the customer's power supply, the charging cable, the high-voltage wiring between charge inlet and charger and finally the charger itself. Stellantis lists P0D27-00 as Battery Charger 1 Input Voltage Too Low in the integrated dual charging module of the 2021 Jeep Wrangler 4xe, with MIL, no level 2 charging and in some cases a tripping house breaker; the remedy is new IDCM software along with several other modules. Later notes ask for a test charge after clearing before an IDCM is replaced. Too high an input voltage is P0D28.
P0D27 at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.3 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0D27
- AC charging does not start or stops
- House circuit breaker trips when plugging in
- MIL
Common causes of P0D27
- Most likelyWeak or overloaded AC supply at the charging location
- PossibleFaulty charging cable or EVSE
- PossibleCharger module software (Stellantis IDCM reflash)
- Less likelyDamaged wiring or loose contact between charge inlet and charger
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0D27 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 27 | The exact fault in that area. |
What to do next
- Note P0D27 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 P0D27
What does P0D27 mean?
P0D27 means "Battery Charger Input Voltage Too Low". P0D27 says the AC voltage reaching the on-board charger sits lower than the charger accepts while charging is permitted. It is a generic code, so it means the same on every make.
Is it safe to drive with P0D27?
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 P0D27 fail an emissions test?
P0D27 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 P0D27 to fix?
Difficulty: medium. A typical repair takes 0.3 to 4 hours of work. This is a job for a workshop.
Will P0D27 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
