SUBJECT:
Flash: MIL Illumination - P1128 Closed Loop Fueling Not Achieved - Bank 1
NOTE:
THE StarSCAN must be operating at version 6.05 or higher when the module is reprogrammed.
OVERVIEW:
This bulletin involves selectively erasing and reprogramming the Powertrain Control Module (PCM) with new software.
MODELS:
2006 (PT) PT Cruiser/PT Cruiser Convertible
NOTE:
This bulletin applies to vehicles equipped with a 2.4L Naturally Aspirated engine (sales code EDZ) and a manual transmission (sales code DD5) built on or before December 20, 2005 (MDH 1220XX).
SYMPTOM/CONDITION:
The MIL may illuminate due to Diagnostic Trouble Code (DTC) P1128 - Closed Loop Fueling Not Achieved - Bank 1. This condition can occur when the engine is started in cold ambient temperatures between 14° F (-10° C) and 32° F (0° C) and allowed to idle until warm.
DIAGNOSIS:
Using a Scan Tool (DRBIII(R) or StarSCAN(R)) with the appropriate Diagnostic Procedures available in TechCONNECT, verify all engine systems are functioning as designed. If DTCs are present record them on the repair order and repair as necessary before proceeding further with this bulletin.
If the vehicle operator describes or experiences the Symptom/Condition, perform the Repair Procedure.
NOTE:
There are two methods to download flash files to StarSCAN(R). The first (preferred) method is to download the flash files to the StarSCAN(R) from the internet. The second method is to download the flash files from the StarSCAN(R) Software Update CD.
