Last day or two the odometer has flashed "CHECK GAS CAP" when I start the car. I've screwed/unscrewed it a couple times still comes back (at least once.) What can cause that message to flash? 2009 V6 Accord...Thanks...

 

Did you reset the message afterward if required? Otherwise, you might just need a new gas cap.

 

Yes I do keep resetting it when it happens, this morning coming into work it didn't flash, fingers crossed...

 

See this thread, turn the gas cap at least 3 times.

Has gone out and not returned for 3 or 4 days now, looks like it got over its little fit...
