I have replaced the gas cap and I checked and cleaned the filler neck at the cap. I was thinking of rigging up my shop vac to create some vacuum or pressure on the evap system. I am an able mechanic, but lack tools (like a smoke gun) so I am looking to improvise using what I have. Any advice or suggestions would be greatly appreciate.
Thanks

I have replaced the gas cap
Did the gas cap test as bad (e.g. old/worn out, leaking)?

Huh? How will that by itself find a leak?
Any advice or suggestions would be greatly appreciate
Please remember that OBD codes are NOT shopping lists. Have you checked for other possible causes of this code?
lack tools (like a smoke gun)
some auto part stores loan or rent them out.
This guy made one out of a jar and bicycle pump:

Thanks for the reply. Everything I had checked stated that the gas cap may be the problem and since it is the cheapest to fix, they all suggested replacement. So I bought a new gas cap, examined and cleaned the fuel filler neck and made sure the cap sealed correctly. The old cap never 'clicked' when tightened. But unfortunately, the gas cap did not stop the check engine light from coming back on. Secondly, several places suggested using a 'smoke gun' to find the leak. I was hoping someone would comment on how I can create a vacuum or pressure in the evaporation system to diagnose the problem with something I have at home, i.e. shop vac, hair dryer, or air compressor. Any suggestions on how to proceed with diagnosing the problem would be greatly appreciated!
Thanks again - Don
I thought I did
I'll try the make shift smoke gun with the bicycle pump and let you know how it turns out!
@donb410 since you have a compressor, you can use that too. You just have to dial down the pressure with a regulator. Personally I couldn't be bothered so I'd just rent one.
It turns out my suspicions were correct. The hose had been pulled off from the charcoal canister. Since the check engine light came on after I left the dealership that fixed three recalls on my Santa Fe, I presume the did, either intentionally or inadvertently. Car is running great now.
