I am getting mixed answers from dealers and repair facilities.
They say it's the Catalytic Converter - Bank2.
But they have difference in opinion of which one is Bank2.
Is it the Firewall or Radiator Side.
Also could it be something other than replacing the Catalytic Converter? Maybe just an O2 Sensor?
Also can I get an aftermarket converter?

Hi:
Bank 2 faces the front of the vehicle (radiator side). However, any of these things can cause this code:

- Three way catalyst converter Bank 2
- Intake air leaks
- Fuel injectors may be faulty
- Fuel injector leaks
- Spark plugs may be faulty
- Improper ignition timing

As far as an aftermarket converter, there are generic ones that are available, but I don't believe they will work on your vehicle. Can you tell me if there are any symptoms, other than the check engine light?

No other symptoms at this time.
It seems to drive just fine. Quick pickup and smooth running.
How would I know if the problem is one of the simple fixes rather than the Converter? They are $1200 just for the OEM Part alone.

The dealer should have checked those items before making their recommendation. If it is running well, my first guess would be a vacuum leak.

Here are directions if you want to try it yourself.
