It is located at the back of the engine near the fire wall. It is gray with a T connector at the top with two hoses coming off of the T and going forward into the intake manifold.

If you don't have poor gas milage and loss of power, the cat is not restricted and not at fault, however, an engine misfire can also trigger that code.
Change the 02 sensor down by the cat first,( it's cheaper than a cat), see if that clears the code, if not, then go for the cat. You will already have a new 02 sensor, so that will eliminate those two. Hope this helped.

Did you check the block box connected to the vent solenoid? There's a hose that comes off it that appears to run nowhere, that's the fresh air vent. If it's blocked it won't allow air into the system which will set the trouble code. If that's clear, the vent solenoid itself is bad and needs to be replaced.
