128:F05 Fault Code

[rtjohnson1982]

Hey guys, hope everyone is getting ready for Christmas. 2007 International 9200 w/ Cummins ISX and few days ago my check engine light comes on and stays on but truck seems to be operating ok. Code is 128:F05 which I think is egr related but I don’t know anything more than that. Thought about changing the egr valve position sensor but didn’t want go swapping parts without an idea of what might be the problem. Thanks for any info yall could provide as this forum has bailed me out more times than I can count!

What is the actual code in insite?

I think your missing part of the code. Pretty sure the 128:F05 is from the dash. It should be followed by another three digit number. 128 means it's a code in the ecm and the f05 is the fault type. If it's egr I believe the third number would be SID 146.

Yes sir you are correct it said SID 146

You need to get yourself the insite program so you can see what the actual cummins fault codes is.
