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.
the light won't reset unless you use a code scanner and reset it. autozone will not let you use their scanner to clear codes, only read them. go to advance, they will let you clear them. and they use the same scan tool.
