Could someone please provide me with a detailed schematic for a 2001 F250 4x4 vacuum line system?

 

Should be under your hood near the hood latch.

 

Thank you. It should be there, but it isn't. I have one 3/8" vacuum tube sticking out of the throttle body and can't find the line that hooks up to it or figure out where it goes or what it does. For now, I plugged the line with a piece of hose and a bolt until I find out. I have a check engine light, but the engine runs well. I compared it to an older Expidition and that approach didn't solve my problem. A good schematic would certainly help. A friend hoped I could solve the problem for him after he switched engines.

 

I am trying to remember what it went to if anything on the 01 I had. What codes are you getting causing your CEL?

Is this the one that you are referring to?

My firend hasn't taken his truck to a parts store where they will run obd 2 codes for free, but it is a great idea. Perhaps doing so will give him an indication what isn't hooked up. We can probably also get a schematic from the Ford garage. He is very busy with college, two jobs, two kids, and the Oregon National Guard. I'll pass your tip on to him this afternoon. If nothing else we'll find an '01 on a used lot somewhere and look. Thanks for your ideas. J.S.

 

Did you look at the picture I linked ?

 

I have not been able to locate any photo link. Thanks for trying.

 

Do u have a pict of the other side of the pict u sent the drivers side of the motor

 

I know this is a old post but if anyone is watching it.... Any way to see where the vacuum lines go that are closer to the side of the battery where the small chamber is and the lines go off it to somewhere.?

 

So the answer is no diagram?

 

If you are talking about the vacume lines that go behind the battery near the fender then yes. One goes to the plastic thing (I dont know what its called) and the other is a vent hose that goes to the front differential to vent it (dont know why ford did that eather but they did) I know that because I just removed my battery and the plastic tray that it sits on today while looking for a vacume leak
Hope this helps you out

 

I dont have a diagram but what were you looking to find on the diagram if someone had one?

 

off the throttle body is a large plug with 3 small lines coming out of it.
one goes to the fuel pressure regulator on top of the passenger side valve cover,
one goes to the passenger side vacuum accumulator for the heater controls,
and the third goes to the driver side, i believe to the EGR.
there are only 3 lines off that intake port.
the line off the vacuum accumulator goes inside the cab to a 2 way splitter. one line goes to the blend door, the other goes to the heat/ac control switch.
it is a very simple system.
