P0E92: Drive Motor B Inverter Voltage Sensor B Circuit Range/Performance

P0E92 is stored when voltage sensor B of the drive motor B inverter gives a reading inside its electrical range that does not fit the other voltage values of the high-voltage system. No manufacturer documents P0E92 publicly. The closest published test is Mitsubishi's plausibility check P0DA4, written for the first voltage channel of the rear motor in the 2023 Outlander PHEV: with the boost converter off, the rear inverter voltage is compared with capacitor 1 and both capacitor 2 channels of the front unit, and a difference of 100 V or more to each of them for 0.2 s counts; the hints name the rear motor unit, battery management and the power drive unit. For drive motor A the same fault on sensor B is P0E8D. A drifting measurement or a wrong reference elsewhere are both possible, so all channels should be compared.

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

MIL and hybrid or EV system warning
Second drive motor switched off, reduced acceleration

Most likely causes

Voltage channel B of the motor B inverter drifts
Internal fault of the motor B inverter or motor unit
Wrong comparison value from battery management or the front power electronics

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 P0E92 means

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

Frequently asked questions

Can I keep driving with code P0E92?

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 P0E92?

The most common causes are: voltage channel B of the motor B inverter drifts; internal fault of the motor B inverter or motor unit; wrong comparison value from battery management or the front power electronics.
