Hey all -
I've got a check engine light with the following code:
P0442 Leak in Evaporative System Detected
I've had Autozone reset the CEL twice now, but the light just came on again this morning. Originally, the guy thought that it might be a loose gas cap, but I've been diligent about making sure its tight.
Does anyone know what the problem could be? Do I need a new gas cap? Is there some other engine part that's gone bad?
Any help is very much appreciated!
