I have a puzzler for everyone. My 2011 base is intermittently throwing a code P219A. Have any of you guys had this code, and what was the ultimate fix?

According to others that have received this same code, it could be caused by a fuel trim imbalance from side to side, caused by a lazy O2 sensor. The sensor is not bad enough to cause a bad O2 sensor code. Check the wiring to the sensors before you start replacing parts. Some clear the code, and it goes away.
