Did a search but everything was coming up as the code being low voltage. When I read the code on the SCT it says Evap Pressure Switch Stuck Closed. I read all the other fixes, like the gas cap, pressure test the system and to smoke it to find the leaks but they were all fixes for the small leak or large leak. Is what I am reading from the SCT the same thing as the small/large leak or is the evap solenoid the one that is stuck and I can just replace that? Or is it something by the gas tank? I did check the hoses and they seem to be okay from what I can reach.
Its an 03 4.7 QC.

 

Sometimes the hoses crack right at the ends where they slip over the nipples and you cant see they are cracked until you take them off.

 

I'll check it out. I did clear the code, and it hasn't come back on yet. I have to do some maintenance soon and will take care of it then. Thanks
