I recommend trying this product before replacing the cat converter and/or evap canister. It has good build quality.

The sensor is installed after the catalytic converter and is compatible with my 2004 Corolla.
90% found it easy to install
I installed the sensors myself and it was pretty easy. I passed the smog test with no problem.
The installation was very easy and required no removal of internal molding. The connector is located on the left side of my passenger foot area and I need to pull the carpet away at the top to access it.
