2009 2.4l O2 sensor
 

Hey guys, love the site. Long time reader, first time poster.

I'm sure it's here somewhere, I'm probably not narrowing my searches well enough....
The code reader I have tells me the 2009 2.4l's O2 sensor is "high voltage" and that it's "bank 1 sensor #2". Can someone tell me where that is located? Tell me... Or maybe post a picture / diagram..
Thanks a ton.

Follow the exhaust since its a 4 cylinder there's only 2 , the second one in line is #2

Sensor 1 is before the cat.convertor sensor 2 is after the cat. Convertor what was the code number?

Here a pic you can see the port that sensor 2 threads into in the pipe after the cat.

I had the same code, it showed up after installing a K&N cold air intake kit. Coincidence? I sent pics of my install to K&N. The install was last fall and since then I'm now running 91 octane and the code hasn't come back yet. Lots of power with the K&N kit but the highway cruising is now 100 kph instead of 120 kph to get the same fuel economy. Any one have a fix or a point in the right direction.

Is that an after market pipe? Where and how much? Is there a front port?
