Q: Check engine light is on, need help with codes

asked by on May 12, 2016

A couple months ago, the Check Engine Light came on, and I took it to Auto Zone who helped me to retrieve the codes. Two codes came back about the gas cap being loose, so I tightened it. I know with Jettas, most of the warning lights have to be turned off by hand. I didn't do that, and figured I would have my car inspected later. So I did, and then the mechanic who tried looking at the car said that too many codes are showing up to pass it. I went to Auto Zone again and now the diagnostic tool came back with 7 codes. Here are the codes:

• P0456 Evaporative Emission System Leak Detected (Very small leak) • P0442 Evaporative Emission System Leak Detected (Small Leak) • P0441 Evaporative Emission System Incorrect Purge Flow • P0456 Repeat • P0442 Repeat • P0456 Repeat • P0442 Repeat

I have tried researching this but I am not able to find out the cause of this. Any suggestions? Can this be fixed at home?
