What's up people?

My SES Light came on recently and I had the code pulled at Autozone. Got code "P0455" which according to their reader has something to do with emissions control.

Any ideas on what is causing this? Anyone else get this code before?
Is it time to visit the dealer? Car is still under warranty so I shouldn't have to pay for anything at the dealer, right?

 

its either the cat convertor or the o2 sensor

 

P0455 is often just a loose gas cap. Make sure it's tight and either drive the car for a few days (take a while to reset) or disconnect the battery for an hour or so to reset the code. Chances are it won't come back on.

 

maybe the code i was referring to was 0450..sorry for the misunderstanding
