This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer thinks the sensor that checks the temperature of a part that controls the electric motor is getting a signal that's too high.
The P0BD9 code indicates that the signal from the temperature sensor in the drive motor inverter is reading higher than expected, which could mean a problem with the sensor or its circuit.
The drive motor inverter temperature sensor D measures the temperature of the inverter, which controls the electric motor. A 'circuit high' condition suggests the sensor is sending a voltage signal that is higher than the normal operating range, indicating a potential fault in the sensor, wiring, or connections.
• Check Engine Light is on
• Possible reduced performance of the electric drive system
• Overheating warning for the drive motor inverter
• Faulty temperature sensor
• Wiring issues such as shorts or open circuits
• Bad connections in the sensor circuit
Inverter: A device that converts DC electricity to AC electricity.
Sensor: A device that detects or measures a physical property and records, indicates, or otherwise responds to it.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connections to the temperature sensor.
• Test the temperature sensor for proper operation.
• Replace the faulty temperature sensor.
• Repair or replace damaged wiring or connectors.
• Clear the code and test drive to ensure the issue is resolved.
• OBD-II Scanner
• Multimeter
• Basic hand tools

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regular maintenance checks
• Ensure proper cooling system function
• Check wiring and connections for wear
Sensor Issue
• Avoid driving aggressively until the issue is fixed.
• Schedule a service appointment to diagnose and repair the issue.
Repairs may be covered under the vehicle's powertrain warranty if applicable.
This code has been associated with hybrid and electric vehicles, particularly as they age and components wear.
Moderate – While the vehicle may still be drivable, it's important to address this issue to prevent potential damage to the drive motor inverter.
Ignoring this code may lead to decreased vehicle performance and potential overheating, which could be unsafe.
• Vehicle at operating temperature
• Drive motor inverter under load
The drive motor inverter temperature sensor is typically located near the inverter assembly, which is often situated in the engine bay or under the vehicle.
Q: Can I drive with a P0BD9 code?
A: It's possible, but not recommended, as it may lead to further issues with the drive motor inverter.
Q: How do I clear a P0BD9 code?
A: After repairing the issue, use an OBD-II scanner to clear the code. If the problem persists, the code will return.
