Light came on and found 0190 code (rail pressure sensor circuit malfunction). Truck was running crappy. changed fuel filter which seems to have fixed problem. Light has since gone off but my problem is when I key it for codes it still gives me 0190. Is there a way to reset this? Does this mean that I did not fix problem or do I need to pull off MMM box and have dealer reset or check out. I am anti-dealer but I am also anti-fing my truck up. Thanks

 

try unhookin both batteries for about 30 minutes,then touch unhooked + and - together.this what i was told anyways

 

Auto zone
They can clear the code with their scan tool
