P1456 code
 

I was getting code 90 so I had it pulled

getting a
P1456 Evaporative Emissions (EVAP) Control System Leakage (Fuel Tank System)
they told me it was the gas cap so I bought a new one form autozone

light is still on

what else do I check?
does the light reset itself or am I supposed to do something?

Re: P1456 code
 

disconnect the battery for 1 min then reconnect.

Re: P1456 code
