Hey everyone I'm having some issues with my 03 Tj 4.0. keeps throwing a code for the leak detection pump pressure switch. I have emissions here in ct and my test date is right around the corner. So far I have checked over most of the Evap lines and also changed the LDP . Haven't found any noticeable leaks or issues jeep run like a top no issues at all other then this code. I'm banging my head on the wall here trying to diagnose the cause. I was hoping for some help for all my fellow jeepers. Thanks in advance

Oh btw the gas cap is new also

It's not locking cap. It was a replacement cap from autozone. The seal on the cap looks pretty good not dry or hard. seems to be making a good seal
