What is your question?
I've owned this car for 4 years now and since I bought it I've replaced the gas cap 5 times trying to get the "check gas cap" notice to go away. As well as the check engine light. I had the car's computer checked at auto-zone and their code reader said it had code P0455- a large emissions leak. the car will go days after the tank has been filled completely, with no check engine light, and no check gas cap messages. but as soon as soon as it drops below full, all the lights and warnings come on again. this has been going on for years. IT'S NOT THE GAS CAP! could it be the FUEL TANK PRESSURE SENSOR?????? help!!! please?!?!?!?!?!

Have a MECHANIC scan test the EVAP system.... Zone cannot do this, they have no scan test equipment and no MECHANICS!! They have parts sales people and a code reader but that doesn't help much! The mechanic may want to perform a smoke test to help locate the leak as well... It's got to be tested!!!
Same issue. I've had the cat replaced, O2 sensor, smoke test found leak in vent valve after 0455 code. Today after 3 days, check engine light on again. Out of money and getting aggravated.
