service engine soon light
Hi All,
My 2005 Bonneville's service engine soon light is on. I think my wife left the gas cap loose when she filled the tank. What is the best process to use to get the light off if this is indeed the problem? Thanks, Vic |

Re: service engine soon light
Take it to Advanced or Auto Zone and have it scanned. Write down the DTC's & post back. BTW, tell them to delete the DTC's if they will. If it was only a loose gas cap, you should have no further problems.

Re: service engine soon light
Thanks for the inputs. The problem turned out to be a bad gas cap.
