|P0100 – Mass or Volume Air Flow A Circuit|
|Description: The powertrain control module (PCM) continuously monitors this sensor for concerns. The mass air flow (MAF) sensor is monitored for a low sensor frequency. This DTC sets if the sensor frequency changes below a minimum calibrated limit for greater than 0.5 seconds.
Possible Causes: • Open MAF sensor element
Diagnostic Aids: Install a new MAF/IAT sensor. Refer to the Workshop Manual Section 303-14, Electronic Engine Controls.
