P0BD6Drive Motor Inverter Temperature Sensor D Circuit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- Sensor D is, in GM's hybrid tables, the second thermistor of the motor B inverter, the counterpart of sensor C in the motor A inverter: phase V in the 2016 to 2019 tables, temperature sensor 2 of inverter B on the Volt. Other makers assign the letter differently. P0BD6 is its general circuit code for an electrical fault that the controller does not narrow down to low, high or erratic. No manufacturer documents this exact code publicly; GM reports P0BD7, P0BD8 and P0BD9 instead. CARB requires monitoring of hybrid sensor circuits. Without a valid value the controller cannot protect that inverter and usually limits the motor it drives. Read all stored codes, since several inverter codes often appear together.
- What you may notice
- Hybrid system warning or check engine lamp
- Reduced electric drive or generator power
- Higher fuel consumption in hybrid operation
- Likely causes
- LikelyInternal fault of the sensor inside the power inverter module
- PossibleCorroded or loose connector at the inverter module
- RareSoftware fault in the motor control processor
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
