What does the engine code P0C00 mean?

Definition: Drive motor ‘A’ current low
The engine code P0C00 indicates that the electrical current in your motor is low, which can affect the motor’s ability to generate high torque
The proportion of generated torque and the amount of current is typically close to equal. This proportion allows your vehicle to operate efficiently, even at high speeds. Simply said, torque is your motor’s ability to do work. 
Without torque, you won’t be going anywhere fast.

How much will it cost to fix?

It takes roughly one hour of labor to diagnose the P0C00 engine code. Additional labor charges to repair will vary based on the identified cause, the vehicle’s make and model, and the motor type.

  • Faulty hybrid vehicle motor assembly
  • Hybrid vehicle motor assembly harness that is open or shorted
  • Hybrid vehicle motor assembly circuit with an inadequate electrical connection

The P0C00 engine code is only designed to tell you that your motor has a low current, not why your motor has a low current.

Can I fix the P0C00 engine code myself?

After noticing the symptoms and registering a P0C00 engine code with your OBD-II code reader, it’s time to take a look under the hood.
Visually inspect the electrical wiring. Look for signs of damage or corrosion. If you don’t know what you’re looking for, it’s recommended to let your mechanic take a look. This is a complex issue, and the problem can come from a variety of sources.
