P0BDEDrive Motor Inverter Temperature Sensor E Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0BDE means the signal of inverter temperature sensor E is above its valid range. For GM's NTC thermistor with pull-up that reads as an extremely cold phase W in the motor A inverter, typically an open circuit, lost reference ground or a failed sensor. GM sets it below -50 °C, but only after at least 90 s of inverter warm-up at 20 Nm or more, so a genuinely cold car does not trip it: 2.625 of 3.65 s, Type B, two trips, in the 2016 and 2018 tables, 6.25 of 8.75 s, Type A, in a 2019 table. The 2011 Volt uses below -58 °C (Type A), the 2012 and 2013 two-mode trucks below -40 °C (Type B). The controller usually limits power to protect the unmonitored phase.
- What you may notice
- Malfunction indicator lamp and hybrid warning
- Reduced electric drive power once the inverter has warmed up
- Likely causes
- LikelyOpen thermistor or broken connection inside the power inverter module
- PossibleLoose or corroded connector at the inverter
- RareLost sensor reference ground on the sensing board
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
