Defueling

[xmen]

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

04 6.0 Excursion, Dr performance module, air cleaner... recently cleaned the egr valve, no change connected or plugged in...removed the turbo cleaned re-installed no change...not sure if it could be electrical? Scan tool connected showed egr, cleared code no change...

High coolant temp and/or high oil temp is one reason why the truck would defuel.
The oil temp is 253°F (or there about) and I believe the coolant temp is 223°F (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?

If you want, I have the AutoEnginuity and live in the Phoenix area (Surprise, actually) and can scan/datalog it for you.

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...

If I was you, I would take Evil Eye up on his offer. That scanner will catch whats up.

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

Let's see if you can swing by sometime tomorrow and I can scan it for you. I'll PM you my contact info and just give me a call.
