icp sensor????

If it runs the same while unplugged, then that means that the truck is already running on the "default" IPR mapping.
At idle on stock tuning, there should be about 540 or so PSI of injection pressure. Pressure should rise smoothly depending on load. Default values due to a bad sensor or wiring harness will put the idle PSI at about 725 and you will DEFINITELY hear a difference in the way the truck sounds at idle. Also, the ICP will NOT rise smoothly with load.

alright so how do i kno if its working or not? and the truck still has a miss even after new injectors and new cam shaft sensor.

alright well today my truck threw a code, p1211, i looked it up on and that code is P1211 ICP Not Controllable - Pressure Abow/Below Desired..... so apparently the damn thing isnt fcking working and its brand new, what do i do to fix this

i dont kno when it came on. ive got a superchip programer and its got the dtc reader in it and every now and then ill plug it in to see if there are any new codes that come up and last night that code showed up, so i looked it up on the fourm here and thats what it says it is "ICP Not Controllable - Pressure Abow/Below Desired"

i reset the code, and the truck was fine (still has a miss tho) but yesterday i went to drive the truck after it only sat for 3 or so hours and it started with a loping idol, it leveled out after a few seconds but it ran lis complete dog sh*t.... i shut it off and read the codes and it threw the p1211 code again, so i cleared it and started the truck bac up with no lope idol but it still ran bad so i read the codes again and the p1211 code was bac i cleared it once more and has been ok sice. why does it keep doing that
