P0BE4 Code - Drive Motor Inverter Temperature Sensor 'F' Circuit Intermittent/Erratic
Quick Answer
The HV control ECU uses a temperature sensor, which is built into the inverter, to detect the temperature of the motor inverter. Common causes include Faulty Inverter With Converter Assembly, Inverter With Converter Assembly harness is open or shorted, Inverter With Converter Assembly circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0BE4 Description
The characteristic of the motor inverter temperature sensor is the same as the boost converter temperature sensor.
The HV control ECU limits the load based on the signals transmitted by the motor inverter temperature sensor, in order to check the effectiveness of the inverter cooling system and prevent the inverter from overheating. Furthermore, the HV control ECU detects a malfunction in the wiring of the motor inverter temperature sensor, as well as in the sensor itself.
What are the Possible Causes of the DTC P0BE4?
- Faulty Inverter With Converter Assembly
- Inverter With Converter Assembly harness is open or shorted
- Inverter With Converter Assembly circuit poor electrical connection
- Faulty HV Control ECU
