P0101

DESCRIPTION
The Mass Air Flow (MAF) sensor is located near the air cleaner

The sensor measures the mass of air passing through the air intake and generates a voltage signal. The Engine Control Module (ECM) receives the voltage generated by the sensor and uses the signal to set fuel injector base pulse width and ignition timing.

The voltage of the sensor increases as mass air flow increases.
