check engine light codes p1135, etc
 

Good morning,
First time poster. Have a 1999 Camry CE 4cyl. 100k. Throwing p0125, p1130 and two p1135s. Could it be the bank 1, sensor 1 (the one closest to the radiator)? Had the a/f ratio sensor replaced 2 yrs. ago, is it the same thing? Sure would appreciate any info, suggestions.
Thanks in advance!
forgot to add, getting some blue smoke on start up sometimes
