THANK YOU, THANK YOU. Now how do I find out which part number for which sensor? For example, the Amazon part referenced in this post is for an "A/F" sensor. Will that work for the drivers or passenger side? Or is it only for the drivers side? I'm having a hard time figuring out which exact part number works for which side and type.Yes.
Sensor 1, aka A/F sensor is before first cat.
Sensor 2, aka o2 sensor is after first cat, before 2nd cat.
Bank 1 is passenger side, bank 2 is driver side (for a LHD FJ, lol).
