P0BCDGenerator Inverter Temperature Sensor A Circuit Range/Performance
- 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
- P0BCD flags a generator inverter temperature sensor A whose signal is electrically valid but does not fit the operating state, for example a value stuck at one temperature or far from the other temperatures after a long soak. Ford documents this exact code: on 2020 Lincoln Aviator 3.0L hybrids built up to 18 July 2020, P0BCD stored in the inverter system controller (SOBDMC) lights the MIL and is caused by software; the fix is reprogramming that module. Patents by Hino and Mitsubishi Electric describe how such checks work, comparing heat generated in the inverter with the measured temperature change or detecting a stuck sensor. Circuit faults go to P0BCE or P0BCF instead.
- What you may notice
- Malfunction indicator lamp
- Often no noticeable change in driving
- Hybrid system warning message possible
- Likely causes
- LikelyInverter controller software (Ford SSM 49120, Lincoln Aviator 2020)
- PossibleSensor drifting or stuck at one value
- RareUneven inverter coolant flow distorting the comparison
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
