Code p2285 ICP sensor question
 

what is the icp sensor and when scanned the code p2285 was referenced to it. can yall give me some insight on the icp sensor as to what mighht be wrong with it and what it does. the truck has an occasional rough idle but will more often then not smooth out. any help is greatly appreciated

Just a sensor, what year truck is it in, I believe they changed locations over the years. 03 and early 04's were on the back of the truck, behind the turbo, I believed 05 and up moved to the passenger side valve cover...

If it fails, it usually makes the truck surge a lot.

03 so behind the turbo and surging is the exact word i would use to describe what it does it will start and run fun then out of the blue will raise rpms and begin to run rough then will smooth out again

looks like a pia to get to on the 03:argh:

I believe it has a silver/gray cover on it, and it is the sensor with three wires going to it, not two. The two wire plug is the IPR.


And since you asked what ICP is and what it does, and since I really had no clue, I took this from a tech from another forum:

ICP stands for Injection Control Pressure. You first need to understand that the injectors in the 6.0L use high pressure oil to operate. The amount of fuel delivered to the cylinders is directly proportionate to the pressure in the high pressure oil system. The higher the oil pressure is, the more fuel that is injected into the engine. The PCM controls this pressure by controlling a regulator (IPR) and uses the ICP sensor to provide a feedback signal to the PCM indicating the injection pressure.

The injection process is actually is a little more complex then that but I wanted to keep my reply related to ICP. The ICP sensor also provides information to the Fuel Injection Control Module to calculate injection timing and it also allows the PCM to monitor the condition of the high pressure oil system.
