DTC DTC Description
P0101 Mass Air Flow (MAF) Sensor Performance
P1441 Evaporative Emission (EVAP) System Flow
During Non-Purge
Correction
If a vehicle is encountered with any of the conditions described above and all of the diagnostic procedures listed in the applicable Service Manual have been performed with no resulting correction, then use a Tech II scan tool to verify what software calibration is programmed into the vehicle's PCM. A PCM calibration enhancement has been released to correct false indication of low engine oil pressure after cold starts and resolve Park/Neutral idle stumble concerns. In addition, this enhancement will correct the false setting of the above PCM DTC codes. If the improved calibration has not been installed, reprogram the PCM with the updated calibration listed in this bulletin.
Important:
All DTCs, calibration numbers, technician observations and customer comments are to be recorded on the repair order in accordance with article 1.6.2 of the General Motors Service Policies and Procedures Manual.
Parts Information
The calibrations listed are electronic calibrations and are NOT available from GMSPO. Calibrations will be available from Techline starting April, 2000, on the TIS 2000 Disk 7 CD ROM.
