What is the proper name of this part?

 

Doesn't it measure the barometric pressure? Not sure what it's called..

It has a rubber hose that connects to a metal tube that runs down the driver's frame rail to the emissions controls behind the tank. It has a vacuum connection that goes to the motor, and another rubber hose that goes SOMEWHERE. (hence the point of this thread)

 

I believe there are two valves for the evap canister. Maybe it's one of them?

Evap Canister vent solenoid (sp?)

 

THAT'S IT! Thank you! I tried to remember this all day yesterday!

Now I just gotta figure out where the other vacant hose goes.

 

Close but not quite. The Evap Canister Vent Solenoid is a smaller valve in the back of the truck at the carbon canister.

The larger one in Tim's picture near the master cylinder is the Evap Canister Purge Valve. Just to keep everyone confused, some Ford literature refers to the ECPV as the VMV (Vapor Management Valve).

The large and the small vacuum lines both go to manifold vacuum but obviously to different ports.

 

^^ummmm WOW!

 

Wow...I thought the purge solenoid was what is attached to the cannister. Bob do you know where the larger vacuum line connects to the manifold? Is your ECPV mounted in the same location, or did you move it to under the battery mount plate like it was on the Explorer?

 

dang! i was close.

 

I ripped the cover off once trying to diagnose another problem...there's a foam sponge filter element inside. It wasn't the problem and I put it back together.

 

Mine's roughly where yours is. The only vac diagram I have is from 98 and it just says to connect both to man vac.

 

those on all rangers bob? cant say i have ever seen one on mine

 

I can't say for sure because I only have a 2002 shop manual. I believe that the three-port VMV purge solenoid assembly is on all of them from 98 on. I think they were a simpler 2-port purge solenoid valve before that.

My 03 has one, so yours should too.

 

hmm ill have to take a look.

 

It's either right in front of the brake master cylinder, or underneath the battery close to the horn mounting location.

 

how could they both go to manifold vacuume doesnt one have to go to the tank to vent the evap system? or is there a third line?

JOSH

 

^^smart*ss

 

Yes, there are three. One comes from the canister and should still be connected. The other two go to manifold vacuum - the large one for fuel vapor, the smaller one for vacuum control.
