I loaned my scanguage to a co worker, he said in his 2006 f-250 6.0 that his deltas are 22 degrees. If this is true would it not trip a check engine light? His lastest flash is VXCF9

I'm willing to bet that there are certain minimum temperature requirements for both parameters for the CEL to be set. Did he say how long and under what conditions he performed the test?

I really think he needs longer driving time. Do you know what his ECT and EOT's were? Obviously the PCM doesn't think he has a problem or his temps aren't hot enough to be of any concern or it would set a wrench light with that strategy.

Does he have an EGR delete?
