The computer shows Gas cup air leak. It looked still in good shape but replaced the cup with a $32 new one, still same problem persists. What are the next troubleshooting steps?

My mechanic already reset the computer, but still the same signal"gas cup air leak"came back.

You will need to get the EVAP system tested. There may be a major air leak. Maybe one of the hoses or the filler tube is damaged.
