After messing around with the green '07 this weekend no codes no issues etc I swapped out my hybrid battery with a newer one and just some general straightening out of things. Went for a drive yesterday and while I was not paying attention going around the corner whatever check engine light came on Scan the code on the fly while driving and got PO136 something to do with a O2 sensor I'm guessing this is the downstream O2 sensor code? From looking at the data or the live stream data I don't see anything that jumps out at me but then again I don't know all the particulars of the live data or the freeze frame data of an O2 sensor No wiring seems to be in any kind of problem I do believe both of the sensors are original and other than that it doesn't look like there's any slices in the exhaust pipe near the converter or anywhere down line as in no damage no leaks nothing 214,000 mi so I guess I'm getting at it's about time to replace the downstream O2 sensor? I think I have one here that I've had sitting here for a while waiting for a vehicle to put it on.
