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?
