less than .80 volt points to a bad ICP sensor or a HPO leak
to determine a HPO leak you would take ICP and IPR% readings
Low ICP with a high IPR% reading would be a Leaker
a mechanical gauge would be used to check the ICP sensor itself to see if its giving a false reading
Some people try an air test of the HPO system to narrow it down to where its leaking
there was a vidio going on it not to long ago
A scangauge would give you both ICP and IPR%

hey Benny I remember you mentioning that if I had the wrong filter or cap for the oil that could cause a problem. If I am understanding what i have been reading the HPO system is supplied to the hpo after it goes through the oil filter. This just popped in my head because the filter Napa gave me had the wrong part number but they said it works on the 03s too I described what you had said to them and they assured me that they have sold hundreds of them to 03 owners with no problems. I am starting to think this is a bunch of bull. But it is the same part number as my old filter that I got from napa. I am starting to think the problem could be in the filter. I am going to take some measurements in the morning before I go buy the scanguage. what do you think?

Do yourself a favor and use an OEM filter. Frams are now OEM filters, but I notice that these aftermarket filers can change from time-to-time. No way to ensure that they don't switch manufacturers to save $$'s, or when patents run out, etc.

great Advice here^^^^^^^^^^^^^
I run motocraft filters all the way around so I dont have to worrey although I may go with Racor core fuel filters next time
A After Market filter has caused issues B4 Its all in the Height of the oil filter if it wont push the oil filter drain closed it BLEEDS off to much oil to the oil pan
best to use OEM filter and cap

I went and bought a motorcraft filter today but I have to wait and get the cap from ford tomorrow. The autoparts store dont stock the oem cap. I am not sure if I can use the caps I have.

I could not find a scanguage nobody around stocks them. I have to give reps to drivin2live for letting me borrow his scanguage Thanks a ton. If I am using this scanguage correctly I am getting a cvi of 4.99 v I think this is the ref voltage. The ipr is at 14.4 and icp at 149 not sure what this is telling me but ill start researching it. the IPR seems to stay constant while th icp jumps around. right when I turn the key on the icp is at 3593 then I crank it and it dives down to around 1000 on the second attempt it was at 134.

disreguard that lol I pulled a tard move and dident have my oil filter in all the way I just set it in there last night to keep dust and stuff out and never twisted it on. So the real readings are ipr 14.4 icp is at 3500 and after a few seconds of cranking it drops to 0. I poured about a quart of oil on the floor the first time through the oil filter housing if this tells us anything.

Right on SEAN awesome that you did that
Looks like Vref is good at 4.99
so do you mean at KOEO = KEY On Engine OFF that You get IPR 14.4%
At KOEO ICP should be 0
It just seems to me that ICP is all over the place does it seem that way to you to
How did the ICP wire harness look

so you tried to start it and the oil filter cap was not on and it got a quart of oil on the floor
If so thats good news you have good LPO flow
the thing thats got me is the ICP sensor reading
at KOEO ICP should be 0psi
There shouldnt be any ICP pressure till you start to crank it

so let me get this straight with the key on you have 3500+ ICP
and when your turning the moter over starter engauged you get 0psiICP
and your giving the SG enough time to update for each reading
