    My 2009 Tacoma check engine light comes on after fill-up and turns off at 1/4 tank. The EVAP system is new, I bought a gas cap from the dealership. Any ideas?

    You're not click, click, clicking the pump, to fill it all the way up, are you?
    After the gas pump shuts off automatically, stop there.

    Go to Auto Zone or Advance Auto and have them read the codes. Then post them here to help us pinpoint what’s going on.
