Subject:
Fuel Gage Fluctuates On Acceleration or Sharp Turns Low Fuel Light Illuminated (Reprogram I/P and ECM)
Models:
2006-2007 Pontiac Solstice
2007 Saturn Sky
2007 Daewoo G2X
Condition
Some customers may comment on fuel gage fluctuation on acceleration or sharp turns when their fuel gage is at or below 1/4 tank level or above 3/4 level. The needle may fluctuate between 1/8 and empty and eventually turn the low fuel light on. The needle will return to proper level after a few seconds.
Correction
DO NOT replace the fuel tank module or the fuel level sensor.
Technicians are to reprogram the I/P and ECM simultaneously using Sequential Programming.
A revised calibration has been developed to address this issue. Reprogram the I/P and ECU with an updated software calibration using the Service Programming System (SPS). This new service calibration is available on TIS2WEB . As always make sure your Tech 2(R) is updated with the latest software version.
These calibrations will be available as an ECM/IPC programming sequence event.
Important:
Technicians have to select ECM/IPC Sequential Programming in the Supported Controllers Screen
Warranty Information
Important:
Currently, the Service Programming System does not generate a warranty claim code after a sequential programming event, when both the IPC and ECM are programmed in the same session. Until the proper codes are generated by the SPS, please use ZZ999 to indicate a sequential programming event. A Warranty Claim Code of "ZZ999" must be submitted on all warranty claims in which the vehicle was reprogrammed.
For vehicles repaired under warranty, use the table.
