Condition
Some customers may comment on the check engine light being illuminated.

A scan tool may reveal DTC P0171, P0300 or P1174 set as current or in history.

Cause
This condition may be caused by the plugging of one or more of the injector director plate orifices which results in a lean condition.

Correction
Important: This condition cannot be corrected by cleaning the injector(s).

Perform an injector balance test using the Active Fuel Injector Tester (AFIT), CH-47976. Refer to the Fuel Injector Diagnosis (w/CH47976) procedure in SI. If any injector is identified as having a lean condition, replace all four injectors with the revised injectors. After installing the new injectors, reprogram the ECM with updated calibration files using the TIS2WEB Service Programming System (SPS) application. There are two calibration part numbers that are valid for "Engine Operation". Select the part number with the description that reads for vehicles with second design injector. The injector has a dark blue overmold color for this repair.

Important: The fuel injectors must be replaced and the new calibration files must be installed to ensure a complete repair. Failure to perform both repairs will result in the customer returning with the same condition.

If a vehicle returns with the same condition after having this repair performed, the technician should first verify that the complete repair was performed before continuing with SI diagnostics.

I've hadthis service done to my car.

I had all three of those codes.

Warranty replaced my injectors(cylnder four injector was clogged/bad).




Anyone else had this problem on here? I know a few people who have had it on different forums.

Thanks for the great information.
I have a 2007 Pontiac G5 (Canadian Model) with the 2.2L Ecotec engine.
Does this repair apply to the 2.2 as well as the 2.4?
Thanks!
