Defueling

What would cause the 6.0 to be in a de-fueling mode?

High coolant temp and/or high oil temp is one reason why the truck would defuel.
The oil temp is 253F (or there about) and I believe the coolant temp is 223F (give or take a few degrees). There is also a strategy that will defuel while throwing a P012F code for the temperature differential between the oil/coolant.

Cleared what code? What exactly was the code?

I cleared the code that referenced the egr...I did have a code that referred to high oil temp...I read here that i needed to check the connection to the sensor, clean it and plugged it back in, cleared that code and it has not come back, approx three weeks ago...

I would really like to take you up on your offer to scan, I live in central Phoenix...Thurday I checked the FICM and it was at 39 to 40 volts, should be 46 volts...went to strickley Diesel Friday and picked up the Swamps FICM and install last night, not much different, a little disappointed...Also disappointed at Stickley Diesel, after I puchased the unit I asked if they could check codes for me, they said sure for 87.50...I passed, i would rather apply the funds to my own scanner...Let me know...Thanks
