Need some help with some vacuum lines..
There are two small hard and very brittle vacuum lines that are in the main wiring harness. They hook onto the intake manifold on the passenger side and have a check valve that joins them to the intake.
As I was fixing my intake gasket leak one of them broke. It broke off inside the wiring harness. so I then opened the harness up and tried to pull it out far enough to get a hose on it. but every time I tried to do so it would snap off again. I chased the dang thing all the way down to the firewall and I can no longer see it or even feel it. But I know it's in the harness somewhere. I think that the only way I am going to be able to fix this is to just find out what it goes to and then run a new line. Can anyone tell me what these go to? Now that the one is broke, I capped off the line coming out of the intake to stop the vacuum leak but now after about 30 - 40 minutes of driving I get a check engine light. I'm going out right now to pull the codes. Help please..........

I don't know if this will help you but, that check valve is a divertor valve (I broke the same line too) and it works with the air vent selector on your dash. The line runs into the back of the selector somewhere. I will check the manual and see what I can find

I just checked the manual, It really doesn't show much. The best I can tell you is the line runs to a connector behind the panel and that connector runs into a tree of connectors. If it's the same line I am researching, It is referred to as vacuum source from engine. Your opportunity to make an easy fix may have passed if you can no longer reach the line. I used a slip on hose connector and joined two hard lines together to repair mine. I also used a weatherstrip adhesive to keep everything together. Man I hope you get to it from the firewall side. Good luck

I did pull the codes but thatnks to some strange internet problem I was not able to get back on here until now.
The code I pulled was 52.
And from what I can find it is.
52 Oil Temperature Circuit (Low Temperature)
52 Check connections at the oil temperature switch. If OK, replace switch
I then checked the oil temp and it did say "Low" ... so it looks like the code does not have to do with the vacuum line.
