P219C

Cylinder #1 Imbalance Error

DTC P219C, sometimes indicated as P219C00 is an OBD diagnostic trouble code indicating a manufacturer-specific fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing cylinder #1 imbalance error.

The engine control module (ECM) has determined that there is an imbalance in the cylinders. This could be due to a variety of factors, such as a misfire, a leak in the induction system, or an incorrect air/fuel ratio.
There are a few things that you can do to try to correct the imbalance. First, make sure that all of the cylinders are firing correctly and that there is no leakage in the induction system. You can also try to adjust the air/fuel ratio to see if that helps. If the imbalance still persists, then you may need to have the engine checked out by a mechanic.
