my check engine light came on a few times for an evap gross leak. any solutions?

 

Could be that your gas cap is not sealing. Make sure your cap is on tight, remove the negative battery cable for a few minutes to clear the CEL or go through several drive cycles to see if the CEL self clears.

Otherwise, you will need to take it to a dealer to have the specific evap problem diagnosed and repaired. If car is still under warranty, it won't cost you anything other than your time and inconvenience.

 

Check engine light came on for my car... Dealership replaced the gas cap... viola... issue resolved.

 

Fighting with CEL for a month already. Codes 0456 and now 0442 added, - small leak EVAP system. Replaced cap, checked all hoses, purge solenoid valve works well too. Our services cannot understand this issue. Mistery!
