Ok , Got this Code ..po440 ... Mechanic found gas cap was not on correctly .. Cleared The Code...Check Engine light came back on again after 50 miles. Re-Read Code , Still Comming up the same ..po440 . I have been Fueling the Car "Over full " All this time ..I didnt relieze it would have caused Promblems with the emmisions doing this Untill reading other posts about this code. My Question is , Did I destroy the Charcol Canister because the code came back after being cleared? Can I just pull ECU Fuse and reset the system or will the Check engine light come back on? I called Lexus Today and they Want $300 just for the Canister.. I tried pulling the ECU fuse Bit it didnt Reset the light ..Am I pulling the Wrong fuse?

If no leaks are found the tech will test the VSVs. I dont know how many a 97 ES 300 has maybe 2.
No youre pulling the right fuse but the light will come right back on. Hard faults are just that.
