SERVICE INFORMATION

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

CONDITION/CONCERN

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.

RECOMMENDATION/INSTRUCTIONS

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) in SI 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.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
