Reset Check Engine light on 2002 Dodge Ram?
My check engine light came on yesterday. I figured out how to see what the error code is. The problem was a blown fuse (code P1491). I replaced the fuse. Now I need to know how to reset the check engine light. Can anyone advise how to reset the light? Turns out it reset itself after a couple of days. And yes, a blown fuse WAS the problem. Thanks for all the input guys! A: You can disconnect the battery for a couple of minutes. The best way is to erase the code with a code scanner.
