This light was on all the time and every time I had it checked the codes were the same, o2 sensor and purge valve. Every year I would have to pay for them to be replaced and the light would be off for about 5 to 10 min. then come back on. After several mechanics I finally got someone to look into it further. There is a connector between the fuel tank up to the engine that comes loose or even not connected. Unfortunately you have to be under it to look and thats not so easy. Happy hunting!!!

Autozone told us that the car has a 4th cylinder misfire after running tests on it. the misfire causes the car to shake pretty bad in reverse and don't get as good of gas mileage.
