They say it will go off with time, but I don't know. Otherwise you need to go somewhere who has a code analyzer (scanner) to have it reset.

Take it back to the dealer. Make it clear that the light was NOT on when you brought it in so they obviously didn't do something right. HTH. -Jim


Sometimes you can switch the ignition on(do not start), press the gas pedal to the floor 3 times and switch it off. All this within 5 seconds. Crank it and see if it works, if not take it the dealer and clear the codes. Someone may have changed the cap or it is not on right. Joe

Disconnect the positive battery terminal for 30 seconds and when u reconnect it and start the truck the code should be gone. -Cj

There was a plug that they did not plug back in. I don't know if it was a vacuum line or what, but I plugged that back in and it went out the next day

Bought use 2014 ram Pickup . OK Until I filled it first time . Brought it back to dealer . Made appointment for later date to check it .Still under warranty . shop man said it could take a few days for computer to reset .This has been 5 days .Cab is on tight . My fear is I think previous owner or shop cleared the codes to sell it . Is that possible ?Good looking truck 50000 miles


It sure is very possible! What codes are you getting? -Jim

Fuel cap loose and engine light


What code number do you have? For example P0301 is a trouble code that will trigger the check engine light. When the computer is scanned the code that's making the check engine light come on will show up on the scan tool. What I'm trying to get at is if the dealer is telling you the truth. If they won't give you the code number visit your local auto parts store and let them scan the computer for free. HTH. -Jim
