This summary uses the existing diagnostic information shown in full below.
This code means that the part of the car that helps control the electric motor is getting too much power. It's like trying to fill a cup with too much water, and it starts to overflow.
The inverter converts the battery's DC voltage to AC voltage for the electric motor. If the voltage is too high, it can cause damage to the motor or other components.
The P0C79 code indicates that the voltage in the inverter for Drive Motor A is exceeding the expected range. This could be due to a malfunctioning inverter, a faulty sensor, or issues with the electrical system that controls the inverter's operation.
• Check engine light on
• Reduced vehicle performance
• Unusual noises from the electric motor
• Faulty inverter
• Malfunctioning voltage sensor
• Electrical system issues
Inverter: A device that converts DC (direct current) from the battery to AC (alternating current) for the electric motor.
Voltage: The electrical potential difference between two points, measured in volts.
• Use an OBD-II scanner to confirm the code.
• Inspect the inverter and its connections for damage.
• Check the voltage sensor for proper operation.
• Replace the inverter if faulty.
• Repair or replace any damaged wiring or connections.
• Replace the voltage sensor if it is malfunctioning.
• OBD-II scanner
• Multimeter
• Wrench set

Difficult
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regular maintenance of the electrical system
• Avoid overloading the vehicle's electrical components
• Monitor for early warning signs of electrical issues
Electrical System Issue
• Do not ignore the check engine light.
• Seek professional diagnosis and repair.
• Avoid driving the vehicle until the issue is resolved.
Check with the vehicle manufacturer for warranty coverage on hybrid or electric components.
This code is more common in hybrid and electric vehicles due to their complex electrical systems.
High – Driving with this issue can cause further damage to the vehicle's electrical system.
Ignoring this issue can lead to safety hazards and potential legal liabilities if the vehicle fails to operate safely.
• Vehicle in ready mode
• Inverter operation under load
The inverter is typically located near the electric motor, often in the engine bay or under the vehicle.
Q: What happens if I ignore this code?
A: Ignoring this code can lead to severe damage to the electric motor and other components, potentially resulting in costly repairs.
Q: Can I drive my car with this code?
A: It's not recommended to drive the vehicle as it can cause further damage and may not operate safely.
