hay just had a friend that had a garage stop a bring his plug in scanner.run the test on it,it said electrical control psi 700. ipr circuit fault and internal control module reading code 'po603 and injector control pressure p1212 then not enouph pressure to read p1211. any help on this could it be that in line fuel pump restricting it.

 

Any codes stored in the pcm won't have anything to do with fuel pressure.

 

Check in the stickies. There is a thread of trouble codes and lots of other good info. The p1212 is icp not at expected level.

 

Sorry just re read the post. I think p1211 is pressure uncontrollable. That could be an ipr issue. Did you ever check the tin nut? Also did you check the idm for water. It in mounted in the driver side fender

 

i am not to familiar with with the navigation of the site how do i find the stickies,and thanks alot for all youre help

 

If your on a computer they are the top 4-5 threads. On the app it says stickies up top

 

its got anew one on[ipr] but i dont know about the nut, do you have a picture showing the nut in question. the idm is that the comp.box on the finder well if so its new too.

 

sorry but still cant find the stickies must be looking in wrong place

 

We call them "stickies" (some forum sites actually use that term), but here on FTE, they're marked "Read First" in Red. They're the first four or five threads at the top of the section. I THINK the one you're looking for is this one - https://www.ford-trucks.com/forums/1...ostic-faq.html .

Correct, IDM is the MODULE (it's not really a computer like the PCM) on the inner fender, driver's side. Thanks to its ingenious (NOT) location, rain water coming through the hood/fender seam has been known to collect INSIDE the module. Pull it, shake it, listen for water. But the codes are sounding more like it's an injection pressure issue.

 

the readout give me a p063 code witch says its a internal control module/kam error. does any one know what that is.it gave the icp voltage up to level too

 

by the way thanks madpogue i did find the stickies good info

 

Don't sweat a KAM error. KAM means Keep Alive Memory. It's the "volatile" memory in the PCM that depends on constant power to be maintained. Whenever you disconnect the batteries, pull the constant PCM power fuse, or disconnect the PCM, that memory gets lost, and next time the PCM gets power it sets that code.

What was the exact code for the ICP?

 

the cods read po603-p1212-p1211 and thanks for the info,so disconnect the batteries then pull the fuse .do you know witch fuse it is.

 

the guy that had the scanner was not real knowledgeable about it but there was something there that said some pressure was about 270 lbs. on one of the scans,didnt know if it was oil or fuel.did a injector scan to the buss test and it said ok.

 

Fuel delivery is completely mechanical; PCM does not monitor or control it. So that 270 PSI would be hydraulic oil injection pressure. And it would be too low to run the truck. IIRC, minimum is 500 psi.
