Hey y'all! When I first got my 2001 Sport in August of last year, it made the 300 mile drive back home fine, with no issues at all. I wasn't really into this whole CF, actually, didn't even know about it. Anyways, after about 3 days of casual driving (still on my permit then so it'd get driven to school, then back home with the old man) I got this check engine light saying P1494. I chased it for 4 days, then it mysteriously went away. Now, suddenly, It's back again. My Innova CEL reader is saying it's a "leak detection pump pressure switch or mechanical fault" which y'all can clearly see in the picture. Any help on this one?

Had the same issue last week, mine was the rubber 90 degree elbow connector between a vacuum line and the intake manifold. It was all cracked. I replaced it with a generic pcv connector from autozone and cleared the code, and it seems to be fixed.
