OBD Code P219B
 

Hello everyone,

I just picked up my 2014 Mustang GT/CS last week. While driving it Friday evening, my CEL light came on. Hooked up my OBD reader to it and it gave a code of "P219B - Bank 2 Air Fuel Ratio Imbalance."
Can anyone confirm if this is a bad O2 sensor and if this is a common problem?
Any suggestions on what dealership to take it to?
Thanks very much,
