My wife got a CEL on her way home last night from work. She called me immediately and asked if she should pull over. She had no performance issues so I told her to drive home. When she did, I checked and the gas cap, while on, was very loose. I tightened it and now we'll wait and see if it resets (still on for now).
Two questions:
- How many key cycles does it take to reset the CEL after a gas cap "malfunction"?
- Since she got gas on a Friday, and this happened on the following Tuesday, would there be a good chance of this being something else? I'm just assuming the gas cap since it WAS loose, but it seems as if a long time passed before the car tossed a code.
Thanks, Eric
