If the problem is fixed it will go away after a week or so of driving. It
takes several drive cycles. Sometimes you can reset it by pulling the
negative battery lead but that can create other problems so I don't
recommend it unless you know what you are doing. It can be reset with an
OBDII tester if you have access of one. I recommend you wait a week and see
if it goes away. If not take it to someone that knows how to test it.

P1166 is your A/F Sensor heater circuit, unrelated to the EVAP.
Did you know you have at least one TSB regarding the P1456 error? It's
04-002. The fix involves replacing the fuel fill pipe, which is defective.
Make haste to your local dealer! This may still be covered under warranty.
