Mass Air Flow Sensor

This video shows you how to install a new TRQ MAF sensor in your 1997-2003 Ford F-150. The Mass Air Flow (MAF) sensor determines the mass flow rate of air entering your vehicle. A trouble code indicating the sensor is not working properly could be because it is dirty, malfunctioning, or damaged, in which case your vehicle may run poorly or enter limp mode. Fortunately, sensors are typically easy to replace.

This repair was done on a 2003 Ford F-150 Lariat 5.4L Crew Cab Pickup 4-Door 4WD Automatic and the process should be similar on the following vehicles:
1997 Ford F-150
1998 Ford F-150
1999 Ford F-150
2000 Ford F-150
2001 Ford F-150
2002 Ford F-150
