P0DA4Drive Motor B Inverter Voltage Sensor A Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- 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.
- What you may notice
- Plug-in hybrid system warning and MIL on
- Rear motor power limited
- Code returns only after the OBD-II drive cycle
- Likely causes
- 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)
- RareBattery management unit reporting incorrectly
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
