P0DA4: 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. 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.

High severity. Can I keep driving?If the car still runs, drive as little as possible and go to a specialized repair shop. Do not touch the orange cables: they carry high voltage.

Symptoms

Plug-in hybrid system warning and MIL on
Rear motor power limited
Code returns only after the OBD-II drive cycle

Most likely causes

Rear inverter voltage sensing drifts against the other bus readings
Power drive unit faulty (Mitsubishi final repair step)
Underlying fault in the rear motor control unit (P0C7A, P0DA5, P0DA6, P30D1)
Battery management unit reporting incorrectly

What to check, in order

Start with the simplest. You can tick off each step.

Read the codes with a hybrid-compatible scanner and write down the freeze frame data
Compare the reading with other engine data while varying the engine speed.
Make sure the battery cooling air intake is clean
Check the 12 V auxiliary battery, which can also trigger warnings
Leave any high-voltage measurements to a specialized repair shop

Good to know

It can trigger limp mode.
It affects emissions.

What each character of P0DA4 means

P: Powertrain: engine and transmission
0: Generic code: same on every make
D: Subsystem depends on the code range
A4: Specific fault in that system

Frequently asked questions

Can I keep driving with code P0DA4?

If the car still runs, drive as little as possible and go to a specialized repair shop. Do not touch the orange cables: they carry high voltage.

What causes code P0DA4?

The most common causes are: rear inverter voltage sensing drifts against the other bus readings; power drive unit faulty (Mitsubishi final repair step); underlying fault in the rear motor control unit (P0C7A, P0DA5, P0DA6, P30D1).
