driving to work and engine light & ATTS come on. run a diasnostics test at auto zone and code comes up saying "EVAP Emission Control System Purge Flow Fault".
they said it is probably my catalytic. and mines is messed up inside and rattles. any one know why these light may have come on? thanks

 

Reset it by disconnecting the battery for 5 seconds. See if the light and same code comes back.

 

thanks

 

Your CEL will trigger your ATTS system to disable itself.

 

well i took off the battery as told. and both light went away. so even though the light is gone is ATTS still disabled?

 

no light = everything functions normally, if the light comes back on then you know your code wasn't just an intermitant,,
