Hello, did you run a diagnostic check for codes that lead you to replace these componets? Do you have access to a scan tool to run a diagnostic check on the vehilce?

Customer: replied 1 year ago.
After the truck to shut off this time I did rerun the code it showed up at a P0603 Ctrl mod cam error. Previous to this the check engine light was on and was cleared once the ICP was replaced

Ok does your scanner have the ability to look at live sensor data? Also with the P0603 code do you have a a tuner installed/performance software in the pcm?

This 2003 7.3 liter diesel has 160,000 miles on it it's never been run hard its only pulled it fifth wheel well when it starts with all the force of a real 7-3 leader international I am presently running a tuner and I have set it back to stock mode I used it to her now to check for codes all previous codes have cleared except for the internal critical mod can error. When I did check for live data it showed it was all clear. While it was running the critical of appeared after it stopped

Ok, can you look at icp sensor data with the tool, you must have at least 500 psi for the engine to run and verify you have rpm signal since you replaced the cam sensor even though its new it could be defective. IPR at approx 85 percent?

I will definitely check that and see what the responses is. Thank you so much I will check that and get back to you.
