Hey Guys,
2001 Lexus ES300
My CEL is on with the code P1155 A/F Sensor Heater Sensor Circuit Malfunction.
What is the Denso or OEM part number for this particular air flow sensor, I think there are two. Which one do I need for this particular code?
Any tips on removing and installation with this sensor?
Thanks!!

Bank 2 is super easy, search Youtube here's the first one I found listed.
OEM # is 89465-33350 or Denso 234-9021 beware of fakes on Ebay. I've never replaced one but I'm told the front and back banks are the same except for the wire length.

Yep, it's easy. My post from late 2011 when I had to do this mirrors the above.
