Ok, so I was driving home today and my truck did something funny in overdrive. As soon as you would give it say 1/3 throttle it would have this hesitation kinda like a miss to it. It would also do it if you went past 1/3 and then started backing out of it slowly. It only does this in overdrive so could someone maybe tell me what it might be? Also, I figured I would check for trouble codes like I do a few times a week on my Power PDA and it brought up a new one labeled P2290 ICP, can someone tell me what that is? Thanks for all the help!!!

 

Injector Control Pressure Too Low

 

Ok, so by the smile I guess its something I shouldn't worry about??? lol.

 

An injection control pressure (ICP) sensor mounted on the high pressure pump cover sends an analog voltage signal (0.5V to 5.0V) to the PCM for feedback control of the oil pressure.

You might have a biased or failing ICP sensor

 

Ok, thats all I needed to know, thanks for the help!!
