P0BCCGenerator Inverter Temperature Sensor A 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
- In a two-machine hybrid one inverter feeds the traction motor and a second one the generator, the machine that is mainly driven by the engine to charge the battery or start it. Its power switches carry thermistors so the controller can cut current before they overheat. P0BCC is the general circuit code for sensor A of that generator inverter, used for an electrical fault the controller does not classify as low, high or erratic. No manufacturer documents this exact code publicly; CARB requires hybrid components and their sensor inputs to be monitored for circuit faults. Without a valid reading the controller limits generator power, which can reduce charging and hybrid performance. The sensor normally sits inside the inverter assembly.
- What you may notice
- Hybrid system warning or check engine lamp
- Reduced generator output and battery charging
- Engine runs more often or hybrid mode limited
- Likely causes
- LikelyFault of the sensor or its circuit inside the inverter assembly
- PossibleLoose or corroded connector at the inverter
- RareSoftware fault in the inverter or hybrid control module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
