Unknown Engine Problem

[newc5188]

Hello guys... yesterday my truck developed a god awful squeak so I replaced the first thing I could think of, which was the serpentine belt. Lets just say I went through some serious issues with that, alone... Apparently I have an F-150 OHV belt on my truck at the moment.... After I took my old belt off I noticed some serious side rashing and decided to investigate. I noticed my tensioner was a little loose, but I am afraid that fixing this wont solve my squeaking problem. I searched all over the engine compartment armed with a hose and my ear for the squeaking and could not get a definite location.

Okay, this morning (before I replaced the belt) on startup I had the Check Engine light come on... I got that distressed feeling that everyone gets when they see that. I figured that it was the serpentine belt.... I was wrong. I was driving around this afternoon after I changed the belt and noticed a couple of odd things. One the temperature guage is REAL slow to go up. Two my truck seems to hesitate a little bit.

On to the questions....
Can someone post a close up picture of their tensioner?
Can someone post their belt size(or number) for a 4.0L OHV?
How long does it typically take your temperature gage to start up?
Is it possible that my Check Engine light is from the temperature sensor being broken or having a connection loose?
Would a hesitation be related to engine temperature in any way?
Where is the temperature sensor located so that I can check my connections?

Thanks a HUGE amount for any help,
Ian

You need to determine what code triggered the illumination of the CEL.

Here is the tensioner off my SOHC.

The reason I am asking for a picture is to determine if my tensioner is sitting propperly or not. There is a fairly large gap behind the part where the nut is on the assembly. I am trying to be clear but its kind of tough to put into words.. If I cant determine where the problem is my truck is going to Ford this weekend.

Okay.... so I went and got it tested today to see why the Check Engine light came up... Here are the two codes it threw at me. When it was tested it was used in Global OBDII if that matters.

DTC (codes)

P0113
IAT Sensor 1
Circuit High Input

P0340
Camshaft Position
Sensor A - Bank 1
Circuit Malfunction

I think the IAT Sensor one was my fault since after I replaced the belt and hooked up the intake tubing I forgot to put the sensor back in and ran the engine. I don't have the slightest idea about the Camshaft Position Sensor.... Any help with that is much appreciated.

I think I also found the source of the squeaking. I believe it is the alternator and soon as I have a voltage meter I am going to go test that. I will keep you guys posted...

Sorry to triple post but it helps me keep messages and discoveries seperated.

So while searching camshaft position sensor I discovered that it is known to "chirp" and make noises before it goes bad. I have a feeling thats the problem with my truck. All I need is a location... I figure its at the rear of the block and somewhere around the air filter but can someone be a little more specific?
