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.

Test Procedure - Part 1:

Test Procedure - Part 2:

Step 1 - 7:

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