Hey I'm trying to work on my car myself. I have a 2006 Acura tsx. I'm having trouble finding the O2 sensor. Bank one sensor 1. I've looked at all the diagrams and my vehicle and I can not seen to find it. Its says it should be right behind the engine but is not there or and I just over looking it

 

Welcome to the forums. I moved your post reply since you will get better response this way.

 

Dont know the answer but the O2 sensor is definitely attached to the exhaust system. I would jack up the car and look from underneath to see if its on the backside of the exhaust header.

 

Do you have a photo of your car.
Mine is a UK car of similar vintage, and the Air/fuel ratio sensor fits in the downpipe. iirc.

Why do you need to remove it?
