I am trying to check parts of the EVAP and wiring. I have replaced the charcoal filter, checked the vent valve and ground. I need a wiring diagram so I can trace the wires. Does anyone know where I could get one?

Any tips on where to look next on that code?

Anyone know if the OBD checks this system at every start or how often?
Check engine light has been on and off but same code comes up.

 

I'm guessing if that code isn't listed as permanent then it should be at least pending each key cycle?

For free schematics go to AutoZone and view or download from there. If you're doing this sort of work DIY get an EVTM from eBay--well worth the investment.
