Customer Question

2010 camaro L99 auto. P219B Code what is it?

Cylinder (Air-Fuel Ratio) Imbalance DTC P219A / P219B = Bank 1 AFR Imbalance / Bank 2 AFR Imbalance.
ECM monitors the Difference in A/F Ratio between each Cylinder on Bank1 / on Bank 2.

This means that air fuel ratio on one bank compared to the other is not equal.

The first thing to do is to reset the code and see if it returns because these are often false alarms.
