Have not checked yet because I couldn't find my multimeter anywhere.... just got a new one.

If you need the specs, I'll look at my manual and share them here.

Could you do that please?

For the life of me I can't find it in my Factory service manual. It tells me to go to a page that isn't there. I must have downloaded an incomplete one.

Thanks, those are testing for door closed right? Is there a test for door open also?

Yes, I believe so. . I saw no mention of anything other than testing with meter.

So I was poking around and found a hard vaccum line that is either missing a cap or a line and a line near it that is looped to another one that just doesn't look right to me. I pulled up a vacuum diagram but it isn't showing the two lines that are looped only one??

I also found a sensor that isn't connected to anything.

So the big question is what are these?

I may be wrong but I believe your looped vac ports are for the EGR system. . the vacant tube originally would have connected to the passenger side port (P) and the left (E) one would have connected to a solenoid.

Mine are capped but I guess looping them is the same?

Those two vacuum lines looped together, one goes to the vsv for your charcoal canister and one goes to the vsv for the egr valve. I don't remember what that sensor is for though.

Actually I just looked at my spare parts. Looks like that sensor is the temp sensor for the egr valve.

I was about to say the same.

So that sensor is the EGR temperature sensor..... so if it is plugged in and sitting there reading just the temp of the engine bay what would that do.

The EGR has been removed (I just got the car so i'm still learning this engine)


if that one hard line isn't hooked up to wear it is supposed to be i'm wondering what that would do?


And When poking around to make sure the EGR was all gone I found another sensor that seems like it should have a line or something coming off of it.

So now the next question is what is this?

Do you still have a charcoal canister? Either way. . If it's not connected properly or the entire system is missing, you could smell gas fumes from the tank (my guess).

Where is this located? or was it just loosely laying?
