Is the check engine light or the diagnosis the problem on my Scion tc?

So, Its been raining a lot... for the past few days. On the first day of rain I turned on my prized Tc to find the check engine light lit. I panicked and raced to the nearest pepboys. They did a free general diagnosis and pulled the codes. According to them, there was a leak in my emission system. Which was nothing of immediate danger so I resolved to have it fixed soon but not now. This morning, I found that my check engine light was no longer lit. Now i'm extremely confused as to whether there was a problem in the first place. Could it be the electrical tripping out due to the rain? Or do the pulled codes mean there is a genuine issue?
