Let me start off with, I love my Expedition. We have made MANY repairs on it, and now, I failed for what I think was emissions...I was given a code of P0136 at the inspection station. Anyone know what this code means? I looked it up and found a few different answers for it. I was told I need an 02 sensor back in Oct 2013. Not sure if that's what this code is for. Thanks! Also, my truck has 209,248 miles on it, and it's still awesome!

You should have listened back in Oct 2013 and replaced the O2 sensor then

Welcome, and the answer was posted in your other post. Also helps to state year model and engine when posting
