Hi John & Welcome,
Let me give you the test chart for this particular code. If you have a multimeter, you should be able to do some of the tests listed and hopefully figure out what is happening here.
Here is an enlarged version of the schematic that is in the procedure.
Please let me know you find or if you have more questions.
Good Luck & Take Care, Greg A.
I'm out in left field on this, I have no idea on how to work a multimeter, even if I had one.
I will accept your answer and hopefully I can find someone who could do this for me.
In your opinon it is definitely an electrical problem.
Hi John & Thanks for the accept.
After reviewing the procedure again, it looks like most of the entire test process is looking for open or shorted wires between the Powertrain Control Module (PCM) and the EVAP components.
If you have a friend that is familiar with basic electronics, they should be able to help you. But if you have been in there already, replacing everything that you have replaced, you may be able to do a careful inspection of the wiring and connectors and be able to find something loose or two things touching that are not supposed to be.
