Where is the air temp sensor on a Ford MAF?

If the Ford MAF sensor on your car has 4 wires, then it does not have an air temp sensor integrated within it (the air temp sensor will be somewhere on the air duct that connects the MAF sensor to the throttle body or somewhere on the intake manifold. NOTE: There are several different Ford MAF sensors types.

What causes the MAF sensor range to be low?

The source of the problem is the sensor range voltage is lower than normal or required by the ECU to function properly. The most obvious problem is restricted airflow from the air cleaner to the MAF sensor which can be a clogged air filter.
