How to Service and Repair the Mass Air Flow Sensor on Ford Excursion?

Begin any repair process on the Mass Air Flow (MAF) Sensor by disconnecting the battery ground cable. After opening the engine air cleaner you should disconnect the electrical connector which connects to the MAP sensor. Untighten the air cleaner clamp then divide the air cleaner into inlet and outlet parts yet maintain the MAF sensing elements intact to avoid failure. The MAP sensor along with its body receives calibration and repair as a unified unit. To proceed you must first disconnect the MAF assembly yet keep the MAF sensor electrical connection detached and use the nuts to split the MAF sensor away from the MAF sensor plate. When putting back these components keep the engine air cleaner housing grommet fully seated to stop unmetered air from entering the engine. The alignment notch should guide alignment of the engine air cleaner's inlet and outlet areas while checking that wires do not get trapped behind the MAF sensor before reinstalling and tilting the electrical connector upward.

For Ford Excursion cars, the Mass Air Flow Sensor (MAF) has very crucial work because it quantifies airflow to the engine. This is transmitted by various sensors to the Powertrain Control Module (PCM) which then sends signals to the fuel injectors to allow the correct A/F mixture for combustion. Different types of Mass Air Flow Sensors are Vane Meter also referred to as VAF and Hot Wire; Ford Excursion models have employed them. Although the VAF sensor is quite effective, it is capable of limiting the airflow and it is also subjected to mechanical wearing. In contrast to that the Hot Wire sensor is more accurate and flexible in use but it is very sensitive to contamination. The MAF sensor has to be maintained properly as build up of dirt can cause problems such as stalling or incorrect air-fuel ratio.
