What P0D30 means
P0D30 is the high-side partner of P0D2F: the inverter voltage signal of drive motor A stays near its upper limit. Mitsubishi checks it on the 2018 Outlander PHEV with the front motor unit supplied at 8 to 16 V; a sensor output above 4.7 V, which stands for roughly 440 V, for 0.3 s sets the code. The manual first asks whether the rear motor unit also stores P0DA6, because then a genuine overvoltage from the battery or the HV circuit is more likely than one bad sensor; fuse and cabling come next, the power drive unit last. The 2023 model uses 4.05 V at capacitor 1 for 0.16 s and turns on the MIL. A short to the sensor supply is the classic cause on the sensing side. Real overvoltage has its own code, P0C79.
P0D30 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor0.5 to 6 hours
- Clears after repairAfter a drive cycle
Symptoms of P0D30
- MIL and hybrid system warning
- Electric drive switched off or reduced
Common causes of P0D30
- PossibleVoltage sensing in the power drive unit shorted to supply
- PossibleReal overvoltage from battery or HV circuit (both motor units report)
- Less likelyLoose or damaged high-voltage connection
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0D30 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 30 | The exact fault in that area. |
What to do next
- Note P0D30 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 P0D30
What does P0D30 mean?
P0D30 means "Drive Motor A Inverter Voltage Sensor A Circuit High". P0D30 is the high-side partner of P0D2F: the inverter voltage signal of drive motor A stays near its upper limit. It is a generic code, so it means the same on every make.
Is it safe to drive with P0D30?
Drive gently and only to a workshop. With P0D30 the car can go into limp mode (reduced power) to protect itself.
Will P0D30 fail an emissions test?
Yes, it can. P0D30 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0D30 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 6 hours of work. This is a job for a workshop.
Will P0D30 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
