P0E2B: Drive Motor Inverter Temperature Sensor H Circuit High

P0E2B is the upper-limit fault of inverter temperature sensor H. Mitsubishi documents it for the 2023 Outlander PHEV, where sensor H is IGBT sensor 8 at the V-phase H2 position of the front motor unit: a signal reaching 3.75 V for 0.08 s while the unit receives 8 V or more sets P0E2B-00, and the function list shows MIL and hybrid warning light for it. In an NTC circuit with pull-up, as GM uses in its inverters, the controller would read this as an implausibly cold phase, so the cause is almost always electrical: an interrupted signal path, a missing sensor ground or an element that has gone open. Its low-side partner is P0E2A, the U-phase counterpart P0E26. The repair at Mitsubishi is a new power drive unit.

Symptoms

• MIL and hybrid warning light on
• Drive power may be limited

Most likely causes

• Interrupted signal path of sensor H
• Missing sensor ground
• Thermistor element gone open

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. Check the sensor's ground and make sure the signal wire is not receiving voltage from another circuit.
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 P0E2B means

• P: Powertrain: engine and transmission
• 0: Generic code: same on every make
• E: Subsystem depends on the code range
• 2B: Specific fault in that system

Frequently asked questions

Can I keep driving with code P0E2B?

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 P0E2B?

The most common causes are: interrupted signal path of sensor H; missing sensor ground; thermistor element gone open.
