My check engine light is on in my 99 Toyota Camry , I went to Auto Zone they checked it and said Evaporative emission control system vent control circuit faul top what does that mean and how do i fix it
This means there is likely something wrong with your emissions system. Gas vapor leak, or catalytic converter or the like. Ot it could be just a sensor. A 1999 is now considered an old car so it is probably more than just a small sensor.
