2006 Civic SI O2 upstream sensor location
Hi,
I want to replace my O2 sensor on my 2006 Honda Civic SI. The code is telling me it is the O2 upstream sensor. I have searched the web over the last couple of days and can not find a video or an illustration on where the sensor is located on the 2006 SI. I easily found the part online, but no indication of where it is on the car. I checked the exhaust manifold, but I just can not seem to find the sensor nor the cable. Any help would be appreciated. Thanks so much. Brian

The upstream sensor (air/fuel ratio sensor) is located at the front of the catalytic converter under the car. The secondary O2 sensor (also located on the cat) is located further down.
The attached photo is the air/fuel ratio sensor connector, located at the rear of the engine compartment.
