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.

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

Symptoms

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