Fig. 1: Blow through the sampling tube (A) when testing the MAF sensor
Uncover the rubber boot on the sensor side of the harness connector.
Remove the intake duct from the sensor.
With a high impedance voltmeter, check for voltage between the white wire and ground while blowing through the sampling tube in the sensor. Voltage should be between 0.5-1.5 volts. If not, replace the sensor.
Turn the ignition OFF. Install the intake dust and recover the connector with the rubber boot.

Do you think that you could tell me how to test the maf sensor for a 1999 ford f250 lariat? Also, is there any way to test the coolant temp sensor? If so please explain.
