Ford MAF Sensor Testing, Ground & Signal
Testing the Ground Circuit of the Ford mass air flow sensor.
The Ground circuit connects at the Battery Negative Terminal, and in this test, you'll make sure that the wire is actually doing its job. Here's how to test the ground.
Turn key to the OFF Position. With the Multimeter in VOLTS DC mode. Connect the BLACK Multimeter test leed, to the circuit identified with the letter B, as shown in the video. Connect the red leed to the battery positive terminal. No need to turn the key to the On position, since the Multimeter should automatically read Battery Voltage as soon as the connection is made. If the Multimeter registered 12 Volts, This tells you that this Ground circuit is OK.
If the Multimeter DID NOT register 12 Volts, The mass air flow sensor is not the problem. Without a clear path to Ground in this circuit, the Ford mass air flow Sensor will not work.
THAT WAS JUST an excerpt of this video. It goes into details on specifically testing the FORD MAF sensor. Get the scoop here.
