    My check engine light came on and the code it is throwing is a P1135. The most likely problem is a bad 02 sensor since my 2001 Tacoma 3.4 V6 has about 130k on it. The bad sensor is in Bank 1 on the passenger side by the cat converter I believe that is what the Mechanic diagnosed. I want to try to fix this myself. Do you guys have any experience changing the 02 sensor or helpful hints with where to find parts and how to videos?

    If I remember that code is for the heater side of the O2 sensor.
