01 sonata gls v6...code po455, po442. what are these and how can I pass emissions test in arizona

If you have an EVAP leak, you will get the following codes:

1. P0442 evap emission control system leak (small).
2. P0455 evap emission control system leak (large).

If these codes come up, you need to trace the leak. The most common place for the systems to leak besides the gas cap is at the service port under the hood, the hoses at the purge solenoid, and the hoses around the fuel tank. Check all your EVAP hoses from under the hood , all the way back to the gas tank. You can repair a split hose easily. Buy some 14.5mm EVAP hose at the auto parts store. Just cut the split or cracked section out and attach the new hose.
I can only say that u must fix the code issue and light to pass state emission test, if u reset the light they will know, the system will tell the tester that the system is not ready, this will cause a fail.
