This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with a sensor that checks the temperature of a part that helps control the car's electric motor. It's like a thermometer for your car's electric parts, and it's not working right.
The P0BDC code is triggered when the powertrain control module (PCM) detects an issue with the temperature sensor circuit for the drive motor inverter, specifically sensor E. This sensor monitors the temperature to ensure the inverter operates within safe limits.
The drive motor inverter temperature sensor E is responsible for measuring the temperature of the inverter, which is a critical component in electric and hybrid vehicles. The inverter converts DC power from the battery into AC power for the electric motor. If the sensor reads outside of its expected range, it could indicate a faulty sensor, wiring issue, or an actual problem with the inverter's temperature.
• Check Engine Light is on
• Reduced vehicle performance
• Overheating of the drive motor inverter
• Vehicle may enter limp mode
• Faulty drive motor inverter temperature sensor E
• Wiring issues or poor connections in the sensor circuit
• Malfunctioning drive motor inverter
• PCM software issue
PCM: Powertrain Control Module
Inverter: A device that converts direct current (DC) to alternating current (AC)
• Use an OBD-II scanner to confirm the code
• Inspect the wiring and connections to the temperature sensor
• Test the sensor for proper operation
• Check the drive motor inverter for overheating
• Repair or replace faulty wiring or connectors
• Replace the drive motor inverter temperature sensor E
• Update PCM software if necessary
• Replace the drive motor inverter if it is faulty
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regular maintenance checks
• Ensure proper cooling system operation
• Avoid excessive loads on the vehicle
Sensor Issue
• Avoid driving the vehicle until the issue is resolved to prevent further damage.
• Consult a professional mechanic for accurate diagnosis and repair.
Check with your vehicle manufacturer for warranty coverage on hybrid or electric vehicle components.
This code is more common in hybrid and electric vehicles due to their reliance on complex electrical systems.
Moderate – It should be addressed soon to prevent potential damage to the inverter.
Driving with an unresolved issue related to the inverter can lead to reduced performance and potential safety risks.
• Vehicle in operation
• Engine at normal operating temperature
The drive motor inverter temperature sensor is typically located near the inverter assembly in the vehicle's engine compartment.
Q: Can I drive with a P0BDC code?
A: It's not recommended to drive with this code as it can lead to overheating and damage to the inverter.
Q: How do I reset the P0BDC code?
A: After fixing the issue, you can reset the code using an OBD-II scanner.
