Any chance you did not have the fuel cap tight? Once the code sets, you need to have it cleared (or a unit like the Aeroforce to clear it yourself). Any number of locations for small leak not allowing the appropriate pressure build-up in fuel tank. Also for 2.0 there is a check valve that can leak.

Fuel cap is tight and okay & I cleared the code with my Innova scan tool.
IF code comes back - I would like to know in advance what else can be wrong and how to fix it.

Thanks!
