Re: P0449 EVAP circuit malfunction
Actually never mind. I fixed it. It was a bad connector pigtail on the solenoid. I got a used pigtail from the junkyard and spliced it in, now the EVAP system works perfectly. No more P0449, and it can finally pass emissions.
It turns out that many times when these things crap out, it's because of tiny breaks in the wires on the pigtail. The lines look intact, but inside the insulation they are actually broken. I made sure to grab a couple of spares while I was at the yard.
Don't you hate when that happens?
