I just bought a 2002 caravan se with a 6 flexfuel in it. It failed inspection. I fixed some of the problems but I still hav squealing in the engine area near the pullys. I put a new idler pully on. No change. And I got a 1193 code. Says its manufactuer specific, but no definition to what it is

 

Two sources say P1193 indicates inlet air temp sensor circuit high.

 

Your noise, does it sound diffrent when say the alternator starts to charge the batteries?

 

Thank u for the code def. The squealing starts as soon as I turn the van on. Is still ther as I rev it but faded. My torque wrench broke so wen I put the idler pully on its not torqeud to spec, didnt no if that is also contributing. Wen I spray just the belt with wd-40,i it stops for about a min.

 

Also is that the sensor that is connected to the air filter housing. Thanxs to everyone helping with my problem

 

Never dealt with one. It's got a two pin connector and the wires are dark blue with light green tracer and dark blue with a dark green tracer. Looking at a diagram it appears to be on the back side of the throttle body or just to the left of it on the duct.
