What P0DA4 means
P0DA4 flags a rear inverter voltage that is electrically valid but disagrees with the other voltage readings on the same high-voltage bus. Mitsubishi spells out the check for the 2023 Outlander PHEV: once the power drive unit has at least 8 V, voltage control is off, CAN is healthy and the rear value is available, all three comparisons must fail together, namely capacitor 2 main, capacitor 2 sub and capacitor 1 each differing from the rear inverter reading by at least 100 V, held 0.2 s or longer. Because a single deviating reading is not enough, the rear sensor itself is the prime suspect. The manual first clears higher-priority codes and the rear unit's P0C7A, P0DA5, P0DA6 and P30D1, then replaces the power drive unit. The warning light and MIL come on. The battery-side correlation code is P0DA9.
P0DA4 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 P0DA4
- Plug-in hybrid system warning and MIL on
- Rear motor power limited
- Code returns only after the OBD-II drive cycle
Common causes of P0DA4
- Most likelyRear inverter voltage sensing drifts against the other bus readings
- PossiblePower drive unit faulty (Mitsubishi final repair step)
- PossibleUnderlying fault in the rear motor control unit (P0C7A, P0DA5, P0DA6, P30D1)
- Less likelyBattery management unit reporting incorrectly
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0DA4 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| A4 | The exact fault in that area. |
What to do next
- Note P0DA4 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 P0DA4
What does P0DA4 mean?
P0DA4 means "Drive Motor B Inverter Voltage Sensor A Circuit Range/Performance". P0DA4 flags a rear inverter voltage that is electrically valid but disagrees with the other voltage readings on the same high-voltage bus. It is a generic code, so it means the same on every make.
Is it safe to drive with P0DA4?
Drive gently and only to a workshop. With P0DA4 the car can go into limp mode (reduced power) to protect itself.
Will P0DA4 fail an emissions test?
Yes, it can. P0DA4 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 P0DA4 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 6 hours of work. This is a job for a workshop.
Will P0DA4 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.
