the intake manifold is located on top of the engine, the piece that look like the tubbing is intertwining.
It has a piece between the lower intake manifold and the upper " plastic " intake manifold . If you look at the engine from the passenger side , approximately 1 + 1/2 inches from the engine oil fill cap / tube you can see the valve where you test the fuel pressure just below the " plastic " upper intake manifold
On your 1994 Ford Explorer , I believe the intake air temperature sensor is mounted in the side of your upper intake manifold , not too far from the idle air control valve , as you look along the side of the upper intake manifold towards the firewall (Helpfull)
Look on the intake manifold, it is 1-2-3-4-5-6.Look on the intake manifold, it is 1-2-3-4-5-6.
You won't see it unless you remove the upper intake manifold. It is attached to the bank of fuel injector poppets (aka, the spider).
Stand on the pasanger side of the car with the hood open, the intake manifold in now in front of you. The intake manifold is in two peices; upper and lower, the idle air control in attached to the lower. Look at the left of the lower intake manifold, between the firewall and the intake, its barely visible but you should see some electrical clips, two of the four bolts holding the IAC on, and the IAC itself.
It is screwed into the side of the upper portion of your intake manifold , on the drivers side of the engine , and has an electrical connection to it . Ford refers to it as an air charge temperature sensor .
I found it on 91 V6 under air cleaner on front of the intake manifold. look around the upper radiator hose
look on the intake manifold it will be stampes into the manifold cast.
It is located underneath your intake manifold (so if you look at it from the front it will be behind the back of the motor underneath the fuel intake manifold)
it is located on the drivers side of the engine under the air intake manifold
It is located under the intake manifold. With the hood open, look under the plastic intake manifold and it screws into the engine block. I removed the intake to get at mine. Not a very fun job.
