Default Another code : P0442

Just finished fixing the last CEL and now another comes up. I broke down and bought a decent OBD tool and now have the following code:

P0442 Evaporative Emission Control System Leak Detected (small leak)

And it has this as a pending code:

P0455 Evaporative Emission Control System Leak Detected (gross leak)

I tightened the gas cap and cleared the codes. My guess is they will come back.
Any ideas where to start diagnosing ? I read somewhere it could be a cracked hose or the canister purge (CP) valve ? Thanks for any pointers.

Gas cap bet ya.

I think there's a little rubber washer, look for cracks, etc.

Default P0442 code, any update?

Getting the same code on my wife's 2000 V40. Was the gas cap washer the solution?

Yup, for me, I just had to tighten the gas cap and clear the codes. They haven't come back.
