If the DTC SES check box in editor file is unchecked, you may try enabling it for MAF P0101-P0103 DTCs.
Do you have the alternator for the C10 or one for this 2002 pu? Do you have the loop ring on the negative battery cable, the battery current sensor? The battery current sensor is an amp clamp that measures current flow into and out of the battery. The current sensor then translates flow into a variable duty cycle signal. The sensor then sends this variable duty cycle to the BCM to indicate current flow. The alternator F terminal is a duty cycle signal that reflects field operation. The PCM monitors the F terminal to determine the alternator's load on the engine. The PCM uses this information to adjust engine RPM and alternator voltage set point.
