My 97 f350 has a p1212 and p0340 coming back as soon ad I start the truck. I have icp pressure and rpm when cranking. The Icp is around 850 at idle and icp is 15% the cps is new and the icp doesn't look too old but I'm not sure. Help please! Truck runs ne but cel is on!

Pull the plug on the icp, is there oil in the plug? if so the icp is shot. Also check the wiring by the icp. Something is definately going on with it.

Also the other code is for the CPS, might want to change that out also.

Other than the CEL what is the truck doing...I assume runs like crap with less power than normal, or does it even run?

The previous owner said the icp was replaced but It does Have some oil in the plug. Could be from the old one. As for the cps I replaced It yesterday amf the code still comes back. The truck runs fine. Starts right up doesn't die. Sometimes the idle hunts a bit?

The idle is comming from the ICP issue. What are you clearing the codes with, when they are cleared it throws a CEL right away on startup?

Also try wiggling the ICP plug around so it makes good contact.

Could be a possibility of the ICP plug being bad

I'm clearing it with am oasis scanner and they come back as soon as I start the truck. I think they came up when I did a koeo self test too I don't remember. And what about the cam code and what about the ipr causing problems I'm kinda lost here.
