This summary uses the existing diagnostic information shown in full below.
This code means that a sensor that checks the temperature of a part that helps the car's electric motor work is not reading correctly.
The P0BD2 code is triggered when the powertrain control module (PCM) detects a problem with the temperature sensor circuit for the drive motor inverter, specifically Sensor C. This could mean the sensor is not sending the right signals.
The drive motor inverter temperature sensor monitors the temperature of the inverter, which is crucial for the efficient operation of the electric drive motor. If the sensor readings are outside the expected range, it may indicate a fault in the sensor itself, the wiring, or the inverter.
• Check Engine Light is on
• Reduced vehicle performance
• Possible overheating of the inverter
• Faulty temperature sensor
• Wiring issues or poor connections
• Faulty drive motor inverter
Inverter: A device that converts DC electricity to AC electricity.
PCM: Powertrain Control Module, the computer that controls engine and transmission functions.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for the temperature sensor.
• Test the temperature sensor for proper operation.
• Replace the faulty temperature sensor.
• Repair or replace damaged wiring or connectors.
• Replace the drive motor inverter if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regular maintenance checks
• Ensure proper cooling system function
• Inspect electrical connections periodically
Sensor Issue
• Avoid driving aggressively until the issue is fixed.
• Have the vehicle inspected by a professional if unsure.
Check with your vehicle manufacturer for warranty coverage on hybrid components.
This code is more common in hybrid and electric vehicles due to their reliance on drive motor inverters.
Moderate – It should be addressed soon to prevent potential damage to the inverter.
Driving with this code may lead to reduced vehicle performance and efficiency.
• Vehicle at operating temperature
• Inverter under load
The drive motor inverter temperature sensor is typically located near the inverter assembly, often in the engine bay.
Q: Can I drive with a P0BD2 code?
A: It's not recommended to drive for long periods with this code as it may lead to inverter damage.
Q: How can I prevent this code from appearing?
A: Regular maintenance and checks of the vehicle's electrical systems can help prevent this code.
