21 degrees start then shut down

FMI - Failure Mode Identifier

SPN - Suspect Parameter Number

Basically they are numbers that break down more specifics about the base code.

Yes it could... I believe they need to be torqued to 25 or 27 ftlbs when you install, been awhile. Check Quickserve. Kind of a bear to get too, I did mine when I had the truck serviced. Kid at TA let me throw it in, mine is located behind the fuel filter on my CM-871. With the filter out of the way it was easy. I replaced mine due to it leaking, o-ring failed.

The past 2 mornings 21 yesterday and 40 this morning my oil pressure at start up was 90 psi. Stay that high about 2 or 3 minutes then started coming down. Any thoughts?

Oil pump, oil pressure sending unit, carbon packing? Have you changed the oil filter out, checked for soot or other contaminants, like fuel or coolant? Emissions intact or deleted? If deleted, who did it? Do you have that Inline reader and Insite, that would help.

[Billy7871]

It's got 13k on the oil. I have it checked every change with no issues. It was deleted when I got it 8 months ago. I just ordered the inline 6 yesterday.

[Waterloo]

Who did the delete? Turbo and a Pyrometer (EGT) gauges installed?

[Billy7871]

Someone in Tennessee is all I know. I have a boost and Pyro gauge.

You need to get that file to Rawze, see what they did to that motor, odds are that is your issue. Or possibly the cause, especially if the motor is working against itself.

Waterloo is understating that. YOU NEED TO HAVE THAT DELTE FILE LOOKED AT!! Rawze, Unilevers or Mommaburt can help you out.
