Hello! My name is Jesse Lechuga(Phoenix Az) Thank You For Adding Me!

I have a 2008 IS250 with trouble codes P0031 and P0051 (B1S1, B2S1) I changed out both O2 sensors left side with A Denso 234-9051 right side Toyota Denso 89467-30010 codes will not stay erased! They come back within a minute! Car runs fine, has power and does not hesitate! Any help Will Be Greatly Appreciated! Thank you!!!

Would be best to have a technician pull the new fault codes and go from there. Let them know you've installed both O2 sensors with the part #'s above and go from there.
