P0BDB Code - Drive Motor Inverter Temperature Sensor 'E' Circuit
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 P0BDB 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 P0BDB?
- 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
How to Fix the DTC P0BDB?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P0BDB code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.
