i would check the evap system, vent solenoid and hoses you have a good chance leaking somewhere there

Thanks for your answer however I still need some more help; where is this evap system and solenoid hoses? Are these the vacuum hoses? Thanks again.

The EVAP system is spread from the gas tank to the engine. The code you had was probably for a 'large leak detected' and ONE of the possibilities is the gas cap , but that is as you've found not the only poss. cause. Less aggravation maybe , to have a qualified shop diagnose it. EVAP system leaks can be pesky.
