The odd thing is that the codes indicate that both O2 sensors are defective. I had replaced the carbon canister and filler cap as my mechanic said it might be vapor leak and the vapor pressure is checked when the gas tank is 3/4 full and then again when it is 1/4 full. The codes are indicated by Durametric. When the tank is full I can reset the Check Engine codes but the Check Engine light comes back when the tank is 3/4 full with the same codes.
