[QUOTE="Vader's Fury, post: 673657, member: 473"] New ICP sensor and IPR. Installed today. When driving it drives great for a few mins then I get a P1209 and P1211 code and the truck falls on its face. Will not accelerate and just kinda limps along. If I shut the truck off and restart, it will do the same thing. Run great for a few mins then right back to this. I checked ICP pressure and it will go up to about 1500 quickly then level out there and drop back to 1200 or so and hover there. DC climbs to 50% or so and that is all. I didn't have my ohm meter with me so I Didn't check the harness but I do not see any bad spots or broken wires just from a visual check. When idling I get about 500-550 icp and 5% dc. I know this is lower than it should be. When I unplug the icp sensor, It jumps up to 700-750# and 14% dc. This is much better. Any idea's? Like I said I plan to bring my meter with me tomorrow and ohm out the harness and see if I have a short but any other idea's? [/QUOTE]
