What P0DA7 means
P0DA7 is meant for a rear inverter voltage reading that jitters or drops out briefly without staying out of range long enough for P0DA5 or P0DA6. No manufacturer documents this code publicly. The neighbouring Mitsubishi checks give the time scale: the rear motor unit of the Outlander PHEV needs 0.3 s outside its window for the low or high fault, and the 2023 plausibility test waits 0.2 s, so faster glitches call for a separate detector. Denso's patent US9819293B2 compares the measured inverter input voltage with a value estimated from the motor control loop, an approach that also exposes an unsteady sensor. Likely triggers are a loose low-voltage plug at the inverter, a high-voltage terminal with poor contact, or sensing electronics that fail with heat. The hybrid warning may come and go.
P0DA7 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor0.5 to 5 hours
- Clears after repairAfter a drive cycle
Symptoms of P0DA7
- Hybrid warning that appears and clears
- Brief loss of rear drive power
Common causes of P0DA7
- Most likelyLow-voltage connector at the rear inverter with intermittent contact
- PossibleHigh-voltage terminal at the rear inverter not tightened properly
- Less likelyVoltage sensing electronics failing with temperature or vibration
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0DA7 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| A7 | The exact fault in that area. |
What to do next
- Note P0DA7 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 P0DA7
What does P0DA7 mean?
P0DA7 means "Drive Motor B Inverter Voltage Sensor A Circuit Intermittent/Erratic". P0DA7 is meant for a rear inverter voltage reading that jitters or drops out briefly without staying out of range long enough for P0DA5 or P0DA6. It is a generic code, so it means the same on every make.
Is it safe to drive with P0DA7?
Drive gently and only to a workshop. With P0DA7 the car can go into limp mode (reduced power) to protect itself.
Will P0DA7 fail an emissions test?
Yes, it can. P0DA7 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 P0DA7 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 5 hours of work. This is a job for a workshop.
Will P0DA7 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.
