P0BE0Drive Motor Inverter Temperature Sensor F Circuit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- Sensor F is, in GM's hybrid tables, the third thermistor of the motor B inverter (inverter B sensor #3), the counterpart of sensor E in the motor A inverter; the 2016 to 2019 tables assign it to phase W. Other makers may use the letter differently. P0BE0 is its general circuit code for an electrical fault the controller does not narrow down to low, high or erratic. No manufacturer documents this exact code publicly; GM reports P0BE1, P0BE2 and P0BE3 instead. CARB requires hybrid sensor circuits to be monitored. Without a valid reading the controller cannot protect that inverter phase and usually limits the motor it drives. Read all stored codes, since inverter faults rarely come alone.
- What you may notice
- Malfunction indicator lamp or hybrid system warning
- Reduced power from drive motor B
- Higher fuel consumption in hybrid operation
- Likely causes
- LikelyInternal fault of the thermistor or its circuit 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.
