Hi, hope you can help! Evap Sys Leak.P0442 + 3 other lights I assume are related? VSC Trac, Trac Off and OD Off. See image. Replaced gas cap with non-OEM. Cleared code but light returned 2 days later. See a crack on hose to purge valve. See image. Did not look at charcoal canister under car. What do you think? Thank you!

Yep, this means there is a leak in the system, I would raise the car up and use a flashlight to see if you can find any hoses that are off or have a split in them, the one in the image you have provided does not look like it is leaking.

The P0442 code indicates a small leak detected in the EVAP (Evaporative Emission Control System).

Here is an image of the system so you can see which hoses to check and how it works. If the hoses are okay, I have seen the charcoal canister cause this problem. Check out the images (below). Please upload pictures or videos in your response of any problems so we can see what to help you with.

Sounds good, you can use a smoke machine to help look for the leak which is what most repair garages have.
