Hello,
These codes typically get generated when there is an issue with the ignition harness. When the ignition system is not getting the proper signal.
It could be due to faulty wiring. But it can also be due to an issue with the ECM.
The best course of action would be to take a step-by-step approach and look at different items and specifications.
I have attached the troubleshooting procedure for code P1300 below.
Follow those steps as that can help you determine the issue.
You will need to use a multimeter to complete these steps.
