buns Posted May 2, 2011 Share Posted May 2, 2011 I have a 2002 Lexus ES300. I have a check engine light and did a code scan. I got code P1135. I looked up the code and found out it's an a/f ratio sensor located on bank 1 sensor 1. Can you please tell me what part number I should be looking for and where exactly is this location?
