Want this question answered?
The mass air flow sensor commonly becomes dirty. The sensor can be removed, and the sensor wires can be cleaned to work like new.
It is built into the mass air flow sensor on that year. That will be on the side of the air filter box where the air intake duct work comes out of the air filter box and goes to the engine / Throttle body housing. The duct work is clamped to the mass air flow senser.
your turbo wont work, ie loss of power etc.
It should be located in the duct work between the air filter and the throttle body.
A mass air flow sensor, measures the mass(weight/temperature) of the air the engine is taking in. It does this by heating a wire in the sensor to a certain temperature and as the air flows past it cools the wire. The amount of current it takes to maintain the temperature lets the ECM know how much air it ingested by the motor and calculates the amount of fuel that is need.
The way a flow sensor works depends on the type of flow sensor. The simplest forms like mechanical flow meters use a pressure sensor to measure volume capacity and rate. Essentially a flow sensor measures the quantity of liquid by measuring force created by it's movement. They can do this either mechanically or electronically.
The fuel injection system is designed to work with a manifold pressure sensor, MAP, not a mass airflow sensor, MAF.
From my experience and basic knowledge of owning a 1.8 and 2.2 engine, i believe i carries a MAF Sensor...The 2.2 carries an air flow meter...
It is built into the mass air flow sensor on that year model. You can find it clamped in the air intake duct work that comes from the air filter box and goes to the engine throttle body housing. It will be right at the air filter box when the duct work starts. It will have an electrical connector pluged into it.
It is built into the Mass air flow sensor. That is where the air intake hose comes off of the air filter box and goe's to the engine. Just as it comes off the air filter box, it will be right there. The air intake duct work clamps to it. It has electrical connector hooked to it.
Go online to a large auto parts store and bring up the MAF part number for each vehicle. If the numbers match, your good to go.
Typically Mass Air Flow (MAF) sensors work on the thermistor concept. A current flows through the themistor, heating it, which changes its resistance. The change in resistance results in a new voltage across the sensor. The way that the sensor measures mass air flow is that the mass of the air (amount of air) flowing past the sensor cools it, again changing its temperature. I have been always been amazed at how well MAF's are suited to engines. Cold wet dense air has greater mass than hot dry air, since the parameter that is needed by the engine computer is the mass of air being put into the cylinders each stroke, a MAF works to exactly provide the measurement needed. I hope that the above description isn't too general. Specifically, there are many ways to measure the resistance of the MAF. I don't know which specific method the F-150 uses.
