Code 13

[Ringold24]

Ive had code 13 flash a couple times recently. Idles rough while flashing then it goes away after a few seconds and seems to run fine. Since it’s intermittent, is it likely a bad connection or....? I’m having trouble finding the solution. Thanks in advance

In the FAQ section in this forum, there is a link to the full error codes and their description. Here's a link to it.

I did check that out. I’m looking for insight on which of those 4 possible causes for malfunction are most common. I lack the necessary skills when it comes to diagnosing electrical issues

Is part #9 on this diagram the pressure sensor that trips error code 13?

Or is it #18 on this diagram

Part#18 since intake measures at engine and code 23 would be the code for atmospheric. You could swap them I believe as a test. Most are identical.
