Changing spark plugs on 2002 Dakota 3.9L v6 SLT and I have a hose that I must have knocked loose on accident. It comes out from throttle body and sucks in air when engine is running. Can someone identify this hose and maybe where it goes?

 

You probably wanna post a pic but usually you'll have a line going to the brake booster and also the intake hose. Also a larger PCV related hose. I don't have the 3.9 but those are usually standard.

 

Thanks for the reply.

 

I've never been under the hood of a 2nd gen Dakota but that hose looks like it goes to either the PCV valve or the vapor canister. Air is being pulled into the intake when running as it is on the filter housing.

 

too short for vapor canister I think. Is the hose connected from intake to the driver side valve cover? Looks like it is but i cant tell for sure.

If it is the vapor can, the fitting is directly under the positive battery terminal, under the battery.

 

on my 99 that hose goes to the purge solinid on firewall ..not sure if in diff location on yours
