This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is having trouble getting a steady reading from a sensor that checks how hot a part of the electric motor system is. It's like trying to read a thermometer that keeps jumping around.
The P0BD5 code indicates an issue with the temperature sensor circuit for the drive motor inverter, where the signal is not stable or consistent.
The drive motor inverter temperature sensor C is responsible for monitoring the temperature of the inverter that controls the electric motor. An intermittent or erratic circuit means that the sensor's signal is fluctuating, which can affect the performance and safety of the electric motor system.
• Check engine light on
• Reduced vehicle performance
• Inconsistent acceleration
• Faulty temperature sensor
• Loose or corroded electrical connections
• Damaged wiring or harness
Inverter: A device that converts direct current (DC) to alternating current (AC).
Circuit: A complete and closed path around which a circulating electric current can flow.
• Use an OBD-II scanner to confirm the code.
• Inspect the sensor and its connections for damage or corrosion.
• Test the sensor's output with a multimeter.
• Replace the faulty temperature sensor.
• Repair or replace damaged wiring or connectors.
• Clear the code and test drive the vehicle to ensure the issue is resolved.
• OBD-II scanner
• Multimeter
• Screwdriver set

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regular maintenance checks
• Ensure proper electrical connections
• Avoid harsh driving conditions that may affect the inverter
Sensor Issue
• Avoid driving aggressively until the issue is resolved.
• Consult a professional mechanic if unsure about the repair process.
Check with the vehicle manufacturer for warranty coverage on electrical components.
This code has been more common in hybrid and electric vehicles as they rely heavily on precise temperature monitoring for efficiency and safety.
Moderate – Should be addressed soon to prevent potential damage to the drive motor system.
Ignoring this issue may lead to reduced vehicle performance and potential safety hazards.
• Vehicle in operation
• Inverter under load
The temperature sensor is typically located near the drive motor inverter, which is usually found in the engine compartment or under the vehicle.
Q: Can I drive my car with this code?
A: While it may be possible to drive, it's not recommended as it can lead to further damage or reduced performance.
Q: Is this a common issue?
A: It is more common in hybrid and electric vehicles due to their reliance on inverter systems.
