Hello,
This code can be triggered due to a few different factors.
It could be due to a wiring issue for the ignition coils, faulty crank sensor or circuit.
The best option would be to take a step-by-step approach and go through the possibilities and find out the issue.
I have attached the trouble shooting guide for the code P1320 below.
Go through the steps as that can help you determine the reason for the code.
Please let me know if you have any questions.
Thank you.
