Part 1

Ford has used a Hot-Wire type mass air flow sensor for many years that either comes with or without an internal air temperature sensor. If the MAF sensor has 6 wires, then this is a dead giveaway that it has the air temp sensor integrated inside.

Removal: Caution – The mass air flow sensor hot wire sensing element and housing are calibrated as a unit and must be serviced as a complete assembly. Do not damage the sensing element or possible failure of the sensor may occur. 1) Disconnect the negative battery cable. To remove the MAF sensor, first disconnect the wire harness plug …

The MAF or mass air flow sensor is a main input to the ECM or engine computer form air intake, ... Ford 4-wire MAF sensor wiring tests (integrity testing) - Duration: 16:06.

In other words, the circuit description/job of the wire is the same regardless of Make/Model and color of the wire. IMPORTANT: All of the tests are ON CAR TESTS, do not remove the mass air flow sensor from the vehicle or from its plumbing. Summary Of The MAF Sensor Tests. OK, you're gonna' start by checking the basics.

A Mass Airflow -- MAF -- Sensor in a modern Ford vehicle is located inside the air intake duct. It uses a hot wire element to measure the amount of air entering the engine. The element is cooled as air passes over it, and this information is converted into an electronic pulse to be relayed to the on-board computer, which can then calculate fuel injection functions.

P0102 - Mass Air Flow (MAF) Circuit Low Input The MAF sensor circuit is monitored by the PCM for low air flow (or voltage) input through the comprehensive component monitor (CCM). If during key ON engine running the air flow (or voltage) changes below a minimum calibrated limit, the test fails.
