Subaru P0420 Catalyst Code Troubleshooting and Solution.

In this video I am working on a 2014 Subaru Outback with a 2.5 and CVT. We have done quite a bit of work to this car to solve an ongoing P0420 code. Make sure, especially on a Subaru, that you complete all troubleshooting steps before replacing the catalytic converters as they are very expensive.
