P0E25: Drive Motor Inverter Temperature Sensor G Circuit Low

P0E25 means the voltage of inverter temperature sensor G has fallen below its valid window. In the 2023 Outlander PHEV, Mitsubishi assigns it to the U-phase H2 sensor of the front motor control unit and sets P0E25-00 once that signal does not rise above 1.25 V during 0.08 s with a unit supply of 8 V upward; the MIL is switched on together with the hybrid warning lamp. Mitsubishi states only the voltage. For an NTC element fed through a pull-up resistor, as GM describes for its inverter sensors, a low voltage equals a very hot sensor, so a ground short or a damaged sensing line looks like an overheated switch. Real overheating is reported by separate temperature codes. The opposite limit is P0E26; the sensor is not sold separately.

Symptoms

• MIL and hybrid warning light on
• Motor power limited as if the inverter were overheating

Most likely causes

• Sensor signal shorted to ground inside the inverter
• Thermistor internally shorted
• Damaged sensing board, e.g. after coolant ingress

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. With the connector unplugged, check whether the signal wire is making contact with ground.
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 can trigger limp mode.
• It affects emissions.

What each character of P0E25 means

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

Frequently asked questions

Can I keep driving with code P0E25?

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 P0E25?

The most common causes are: sensor signal shorted to ground inside the inverter; thermistor internally shorted; damaged sensing board, e.g. after coolant ingress.
