Standard Ignition Mass Air Flow Sensor P/N:MAS0256
Standard Motor Products
Standard Ignition MAS0128 mass air flow sensor for the 1997-2004 Ford F-150 V6 4.2L and other vehicles measures the air entering the engine. This complete assembly is extensively tested to OE specifications for long service life.
A dirty or failing mass air flow sensor can show up as a rough idle, hesitation or a check engine light, though other faults produce the same signs. Before replacing it, look over the air filter, the intake duct for cracks or loose clamps, and the connector for bent or corroded terminals, with the engine off and cool. A shop can test the sensor's live readings.
The 1997-2004 Ford F-150 V6 4.2L, the 1996-1999 Ford Taurus V6 3.0L and the 2004 Ford F-150 Heritage V6 4.2L are among the vehicles this direct-fit OE replacement fits, at one sensor per vehicle. It is made for proper fit, form and function.
