Welcome! I can help you with the codes you're seeing on your 2014 EcoDiesel.

- P22FA: DEF (Diesel Exhaust Fluid) tank heater issue. Check or replace the DEF heater, inspect wiring.
- P0420 (Bank 1): Catalytic converter efficiency issue. Likely causes are a failing catalytic converter, exhaust leak, or faulty oxygen sensors.

The two codes could be related due to exhaust system inefficiency.

You may want to start by checking the DEF heater and wiring for the P22FA, and then move on to testing the oxygen sensors or the condition of the catalytic converter for the P0420 code.

Let me know if you need more detailed troubleshooting steps!
