My check engin light is on and truck runs rough on start up after it sets for 24 hours. 03 4x4 6.0L I got a code reader from a friend and came up with P2285 ICP Injector control pressurew sensor circuit low ICP signal is lower than specified value. What is this ICP and how do i go about fixing this problem. Or just bite the bullet and take it to the dealer.

 

Moved to 6.0 Power Stroke forum.

 

if its under 100k, take it to a dealer because the icp sensor is probably leaking oil. its a couple hundred dollars for the sensor itself.
