MASS AIR FLOW SENSOR

The MAFS cause when not working correctly
Lack of Power.
Spark Knock/Detonation.
Buck/Jerk.
Hesitation/Surge on Acceleration.
Malfunction Indicator Lamp (MIL) Illuminated. DTCs P0171, P0172, P0174, P0175 may be stored in memory.
This is a easy test for the MAFS in a Ford Explorer 95
With the MAF sensor electrical connector connected backprobe the sensor signal (light blue/red wire) and the sensor return (tan/light blue wire) at the connector.

Connect the positive lead of a voltimeter to the sensor signal and the negative lead to the return.

Monitor the MAF sensor output voltage while increasing engine speed. The voltage should increase smoothly with no dropouts as the engine speed increases. Listed below are representative values.
RPM Voltage
550 0.8
1000 1.0
1500 1.25
2000 1.4
2500 1.55
3000 1.65
3500 1.9
4000 2.1

In this case the MAFS is working correctly.
