I have a 2010 dodge ram 2500 5.7 Turbo Diesel. My check engine light came on and is still on.
I went to Autozone and they scanned and said the A/F sensor was bad. I ordered one
and put it on. Light is still on. I'm not sure it there is a way to reset the light or not. Can't
find a way on line. I have also changed oil, fuel filter, air filter recently.
