I have a '00 Dodge Dakota. Check engine light came on. Used Google to find out how to check code. U can turn key "on-off", "on-off", then "on" for about 20 seconds. Code will display in digital odommeter. In my case, code P0455. Looked up code on internet at
obdii.com. Then, I looked up a way to clear the code. U can remove the negative cable from battery, then turn key to "on" for several seconds. Clears the codes. All of this for a lose gas cap.
