P0BD8: Drive Motor Inverter Temperature Sensor D Circuit Low

P0BD8 means the signal of inverter temperature sensor D is below its valid range; with an NTC thermistor and pull-up that reads as an extremely hot inverter, usually from a short to ground or an internal sensor fault. GM sets it above 170 °C for 2.5 of 3.5 s, Type B, two trips, on the 2016 Volt, above 159 °C, Type A, in a 2019 table, above 130 °C, Type A, on the 2011 Volt and above 125 °C, two trips, in the 2012 table. Stellantis lists P0BD8-11 for the 2026 Jeep Compass 1.6 PHEV outside the US among the codes behind a no-start with the message Electric Traction System Fault; the repair is the traction inverter of the hybrid dual-clutch transmission.

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

Malfunction indicator lamp and hybrid warning
Vehicle does not start, Electric Traction System Fault (Jeep)
Electric drive power strongly limited

Most likely causes

Shorted sensor or circuit inside the inverter (Jeep Compass PHEV bulletin)
Sensor signal shorted to ground in external wiring, where present
Moisture or coolant inside the inverter housing

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
With the connector unplugged, check whether the signal wire is making contact with ground.
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 P0BD8 means

P: Powertrain: engine and transmission
0: Generic code: same on every make
B: Subsystem depends on the code range
D8: Specific fault in that system
