Vacuum line broken

I have a vacuum line that is coming off of the top of the exhaust manifold and is routed back toward the firewall. The line has become brittle and broke apart. Is there a way to repair the line (splicing it somehow) or will I have to completely replace it? If I have to replace it, does anyone know the name of it so I can find it at the parts store or the dealer?

Vacuum lines are in a few different sizes atake a piece to like a store like napa or a higher line of part sales they have rolls of it for a few bucks a foot just cut a 1/2 inch off an end and take it down there get a few feet more change and replace all cracked frayed lines..mechanics will replace lines and go around with a 2 feet of new line and use like a stethascope to hear for more hissing...check the vacuum lines to your throttle body follow the air cleaner to the manifold its there ..

What is the function of the DPFE in a 2003 ford expedition?

Delta Pressure Feedback of EGR (or DPFE) is the difference or change in the EGR system pressure. The DPFE Sensor reads changes in the pressure of the EGR system.

There's a vacuum line coming off the intake manifold to the EGR actuator. The actuator is on the firewall and it's an electric device controlled by the PCM that modulates how much vacuum pressure gets past it. From there, another hose goes to the EGR Valve. Vacuum pressure opens the EGR Valve, allowing exhaust gases to be pulled from the exhaust manifold, past the DPFE tubes, then back into the intake manifold. When gas flows through the EGR tube, the two tubes leading to the DPFE Sensor get pressurized. There's a differential in the pressure, one tube has more pressure than the other one. The DPFE registers the amount of pressure difference and can tell how much exhaust gas is flowing through the EGR system. It tells the PCM how much is flowing, and The PCM uses this reading to control the actuator.

Cabin heat

Yes, it might be hard to find such a diagram. Short of a factory service manual, I don't know. Perhaps a friendly parts person at a Chrysler dealership might be able to provide you a copy of how the vacuum lines connect, and how routed.
What you generally have is a single vacuum line from the engine going into the firewall and under the dash to the rear of the heater/AC control assembly. The line enters a fixture that can distribute vacuum signals through several hoses. One of those is the hose to the water valve, the only vacuum line that goes back into the engine bay. Selecting heat on the control obviously will send vacuum from the fixture to the water valve. The other hoses or lines connect to diaphragm operated door levers to control where air is sent.

See where the vacuum line for the valve goes back into the firewall. Then get on the inside and try to find that line-it may have broken or come apart. You may need to pull the heater control assembly out to get to the podlike fixture that the vacuum lines sprout from.
An alternative in this frigid weather, a make-do temporary fix, is to tee off a manifold vacuum line from the engine, and run a hose to the water valve. It will be on constantly, but it's winter, hey?

I would check the vacuums under the hood going to the firewall,make sure the vacuum is continual ,look for colasped vacuum lies,or broken vacuum lines,or a check valve in a vacuum line that is near the firewall that is broken or not working.

I have a 2000 Ford Explorer and I used a pocketscan (OBD II code reader and the code is P1400). What does this code mean?

This code refers to the Delta Pressure Feedback EGR(DPFE) sensor voltage. The voltage in this sensor changes as it detects a difference in vacuum. Test: Engine running, so be careful and use proper care! Find the EGR valve and disconnect the vacuum line going to the top of the valve. There should be no vacuum there at this time. If there is then check for proper EVR (EGR vacuum regulator) operation and vacuum line routing. These lines could be broken, cracked or plugged. I have run across many EGR passages in the intake manifold that become plugged with carbon and prevent EGR flow, check this by removing the throttle housing that the EGR valve is bolted to and look at the passages, clean if neccessary, reset Check engine light and see if it comes back on after operation. Hope this helps, let me know.

Gears wont change

Check under the hood near the firewall towards the center of the intake manifold. There is a vacuum line that feeds a valve on the tranny called a modulator valve. This tells the transmissiion to shift out of first gear based upon the amount of vacuum it recieves. It is highly likely that the line was removed or broken while attempting to acess the distributor cap. Thank you.Dana P.S. This vacuum line is usually connected to a solid tubing going down towards the tranny.

Selector knob won't chage from defrost, knob moves but won't chage function.

Probably a vacuum line. Most heater controls are ran by vacuum and their is one vacuum line that goes from the troddle body to the firewall on the passenger side of the car. Check for a broken hose.

1993 Ford Econoline E150, AC and Heat work, however I can't switch vents. All the air is shooting down at my feet. I noticed it look like air actuated switches. Is this true and could there be a hole in...

Air diverter doors are vacuum operated. This problem is generally due to broken vacuum line. Start tracing the vacuum line from entry at the firewall back to engine. Likely goes through some type of canister, especially ball shaped and maybe through a vacuum manifold where several lines attach. Check for leak along all attaching lines all the way to vacuum source at engine manifold. If no problem found then check line from firewall to temp/climate control switches under dashboard and from switch to actuators. Can sometimes be difficult to trace but never impossible. Good luck!

A/c comes out of front defroster. I also found a vacuum hose lose near the front firewall and I cant find out where it goes.

I tried to give you a vaccum diagram but the manufacture will not release that info to outsiders. you need to find where the hose goes to.if you loose vac to the controls it goes to defrost mode.
