Hi,

I got a light on for the P0138 code that told me to replace my downstream O2 sensor on my 2020 Pilot. I got the part and went to YouTube to find replacement videos. I was not successful in finding how to replace this on the 2020 Pilot. I got under the car, but I did not see anything that looked like the O2 sensor that I need to remove. I suspect it might be under the protector plastic guard, but I wanted to check here before I go about removing everything. I am a fairly novice mechanic, but this should be an easy fix. If I am in for more of a hard time than I expect I will escalate the fix. If anyone can point me in the right direction I would be very appreciative. Thanks!
