Air Flow Meter/Sensor: Testing and Inspection
The Tech 1 reads the Mass Air Flow
(MAF) value and displays it in grams per second. It should read between 4-7 on a fully warmed up idling engine. Values should change rather quickly on acceleration, but values should remain fairly stable at any given RPM. A failure in the MAF sensor or circuit should set DTC P0101.
