This guy wasted a lot of time because his scanner incorrectly detected error code P1092.When he had it diagnosed properly,he got different code which pointed him to the exact sensor to replace and thus solved his problem!
In other words,his DTC code was different from yours!You need to be 100% sure, P1092 is your error code?

Check your Kat....!tap it with a metal object and check if theres something loose in there,thats blocking gases!
