Regardless of what color body the MAF sensor has or the amount of wires in the connector, they are all tested in the same way! These come in either a black or light gray body and with 6 or 4 wires in the connector. NOTE: There are several different Ford MAF sensors types. 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. If the MAF sensor has 6 wires, then this is a dead giveaway that it has the air temp sensor integrated inside.
I recommend using a digital multimeter but an analog multimeter can also be used.įord has used a Hot-Wire type mass air flow sensor for many years that either comes with or without an internal air temperature sensor. Testing the Ford mass air flow (MAF) sensor on all of the Ford, Lincoln and Mercury cars and trucks is a very simple test that can be done without a scan tool.
