P0E24: Drive Motor Inverter Temperature Sensor G Circuit Range/Performance

P0E24 is the plausibility test of inverter temperature sensor G: the signal is electrically fine, but the temperature it reports does not fit. Mitsubishi uses the code on the 2023 Outlander PHEV for IGBT sensor number 7 in the front motor control unit, labelled U-phase H2. The check runs only after a soak of at least 600 s, with the IGBTs shut down and the unit fed with 8 V or more, within 1.5 s of these conditions being met. Should it then deviate from either of two other IGBT temperatures by more than 47 °C for 0.1 s, P0E24-00 is logged; MIL and plug-in hybrid warning light both light up. After a long stand all switches should be equally warm, so the code points to a drifting sensor. Mitsubishi's flow ends with a new power drive unit.

Symptoms

• MIL and plug-in hybrid warning light on
• Often no noticeable change in driving

Most likely causes

• Sensor G reads offset against the other IGBT sensors
• Fault on the sensing circuit of the power drive unit
• Uneven inverter cooling, e.g. air in the coolant circuit

What to check, in order

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

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

Good to know

• It affects emissions.

What each character of P0E24 means

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

Frequently asked questions

Can I keep driving with code P0E24?

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 P0E24?

The most common causes are: sensor G reads offset against the other IGBT sensors; fault on the sensing circuit of the power drive unit; uneven inverter cooling, e.g. air in the coolant circuit.
