I got a question on the cct testing. Trucks been running good but whenever I run a cct test on my terminator/aero force scangauge Ive been getting p0272, p0278, p0284. Of those three codes, I can get any combination of them.

Can these be phathom codes?
I haven't pulled the valve cover yet, but I can't think of any connection between them.

 

Before you do the test, get your oil as hot as you can.

 

testing done with oil at 200 degrees

 

Seems suspicious that they would all be on the same side. How's your UVCH / VC gasket connections? When I had the CCT fail code for my #7 injector, it turned out to be a burned up valve cover harness connector.

 

Well I can't do any more testing. My gauge has been restarting on its own for awhile but used to work after abit, now it powers up and goes blank.

So should I try a reflash from aero force?
Or buy another aero force scangauge?
Or just get an analog boost gauge?
