What hooks up to this???/intake

[rwb86]

I need to know what hooks up to this tube under the air intake,im thinking its emission related? im not a mechanic and info would be appreciated.

on 2.9 v6. I have no idea I'm not familiar with this engine. I'll let someone else tell you.really want to know made of Web Search

i just replaced my throttle body on my 2.9 and there should be a thin tube, not sure where it goes but it will just slide up onto it. if you engine is running fine i wouldn't really worry about it.

well i noticed it a few days ago and just capped it,either way it runs the same. but im sure it goes to something.

Looks like the fitting for the hose from the charcoal canister behind the left headlight.

Thanks for the info guys. I'v had several opinions that this leads to the carbon can,so that must be it.

Thats Interesting.....

Mine is hooked to some sort of electronic thing thats bolted to a bracket on the front of the TB. I'll try and post up a pic of it when I get home. Cant say mine is running fine the way it is.....shuts itself off randomly. Been that way since I been tinkering with it.

Yeah that goes to the canister behind the headlight.

quick question vanner,im sure ur truck is similar to mine and was wondering if you knew what the valve coming from the egr tube(just before the actual egr valve) goes to.help would be appreciated.

DifferentialPressureFeedbackExhaust the dpfe sensor its a emission component to monitor egr flow. the main problem with these are moisture contamination, and exhaust heat will be the death of the sensor, it corrodes the sensor inside and destroys the seals around the pressure sensing ceramic disc. i think it usually springs a EGR valve excessive flow code PO402. voltage shud be around .9v +_ a few...if not its out of range.

This is not an obdII equipped vehicle, nor does it have a DPFE sensor. if it's an 86-87 2.9 it will have an EGR pressure transducer. The connection in question is the line from the charcoal canister.

your correct holyford86 sorry you'll have to excuse my incorrect rambling. its been a long day...workin on obdII vehicles. i wish they were obdII! sidenote my 88 isnt equipped with an egr, thank god!
