Hi,

I have searched the forum and sadly got a lot of hits on P1135 and P1155 codes. The conclusion seems to be to replace both 8946748011 (bank 1 and 2) sensors. My local Lexus mechanic (non-dealership) quoted me $703 for parts and labor!!! I have not been able to locate 8946748011 online. I did find Denso and Bosch. From the threads, all the gurus recommend sticking with OEM. Where can I find 8946748011? Thanks in advance!

This is the one I bough and installed 4 weeks ago. It is working great.
