I was wondering what does this mean; It keep up today when I took it to Autozone and I was wondering if anyone knows what this mean; does it mean the Pump is going out or what???? "Evaporative emission control system Fuel Tank Pressure sensor high input"... If you know anything will you leave a post and let me know.

Most common cause is a loose or bad gas cap.

Go turn it until it clicks several times and make sure the codes are cleared.

What if its not the gas cap??? What else could it be?

leaky fuel tank.
