On rare occasions, an SES light may be encountered due to a P219A DTC
In some instances, a P0300 may also be stored.
This may be due to a fuel injector concern on one of the cylinders that a GDS2 fuel injector balance test may not isolate.
This DTC can typically be resolved by following SI diagnostics.
If the GDS2 fuel injector balance test does not isolate a cause for this concern, perform the Fuel Injector Diagnosis (w/CH47976 and CH-47976-500) and evaluate for a rich or lean fuel injector.
In some instances, a fuel injector that has a flow rate as little as 5% greater/less than the other 3 injectors could cause this DTC to set.
If the misfire current counter or misfire graph indicate any misfires, it may be an indicator of the cylinder(s) that is causing the concern.

2013 Tahoe with the 5.3 engine – SES light comes on when the temperature drops below 45 – 50 degrees. The light goes back out when the temperature goes above 45 – 50 degrees. The code that sets is P219a. Dealership replaced an o2 sensor and cleaned the fuel injector system but it didn’t correct the problem which has persisted for 2 or 3 years. I can’t afford a fishing expedition so I’m hoping someone else has experienced the same problem.
