here's an interesting story with a oops at the end
well today started off pretty good went to a wedding and when we got home, the electric was off, a couple got into a fight and the guy thought it was in reverse but it was in drive so he took out a telephone pole...how true that is I don't know but you could clearly see the pole was leaning...anyways this happened at 2pm. we got back from the wedding at 5pm, so me and my wife are socializing with the neighbors and played a game of cornhole, then I got the bright idea to do a little maintenance on my truck, remembering the video about the ICP, I then decided that I would tackle this figuring I'd be done about the same time the power company would, well go the sensor off not much of a problem there, but the tube line on the other hand was a royal pain, took me about an hour to break it loose from the exhaust manifold, yep hadn't been cleaned in oh say the days of Moses, anyhow finally got it out and noticed a hole in the tubing, so now its 1am and the power is finally back on, so heres my questions:
1. in the youtube video the guy says theres a rubber diaphragm or so he thinks there is and not to damage it...I looked in mine and I do not have a rubber diaghragm, so is it broke?
2. what does the icp do? this hole in the tubing has apparently been there since i've owned the truck as you can tell by the pics and this being my first diesel knew nothing about this, I'm going to replace it but just wondering how vital if any the sensor is
