Condition
Some customers may comment on an illuminated MIL light. After the technician performs strategy-based diagnostics, the technician may find the following code stored in the PCM.
DTC Code | Code Description |
|---|---|
P0103 | Mass Air Flow (MAF) Sensor Circuit High Frequency |
Important: All DTC's, 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.
Cause
Certain driving conditions, such as WOT (wide open throttle) upshifts may cause the MAF to exceed air flow parameters and set the code.
Correction
If no vehicle conditions are found when performing the appropriate service procedure for the complaint P-code, then use the Tech II to verify which software calibration is currently programmed into the vehicle's Powertrain Control Module (PCM). If it doesn't match that shown in the new calibration table below, install the appropriate calibration listed below. Test drive the vehicle after repair to ensure that the condition has been corrected.
The calibrations listed below are FLASH calibrations and NOT available from GMSPO. Service FLASH calibrations are available starting with 1998 CD ROM disc 14.
