How to troubleshoot the Mass Airflow (MAF) sensor on Ford Explorer?

Before you blame the sensor for driveability problems, check for wiring issues when troubleshooting the MAF sensor. A hot-wire element is used by the MAF sensor to measure air mass and then it converts it into a voltage signal for the PCM. Faulty MAF sensors can make a car surge or stall in its tracks. To evaluate, measure the voltage from B+ to ground terminal which would be above 10 volts. Consider checking the signal and ground terminals for voltage at idle as well as increased rpm. Apply an ohmmeter to verify broken circuitry in between. Verify that your voltage readings are correct before going any further with your investigation into the wiring harness. In removing the air intake duct, disconnecting the connector, and replacing assembly without separating plastic body from metal ducts is how to replace MAF sensors.

Ford Explorer Mass Air Flow Sensor

The Mass Air Flow Sensor (MAF) found in Ford Explorer is quite important in regulating the air supply to the engine so as to enable maximum performance. This piece of information is transmitted to the PCM for optimizing the fuel injector timing so that; the required air-fuel mixture for proper combustion is achieved. Ford Explorers have incorporated number of different MAF sensors such as Vane Meters (VAF) or the Hot Wire sensors. This VAF sensor, as useful as it is, can choke airflow, and its mechanics can wear out frequently. On the other hand Hot Wire sensor provides high accuracy along with flexibility and the main disadvantage is that it is always prone to contamination. There are other sensors including Hot Film and Karman vortex sensors, although these are constructed with distinctive working principles, yet serve the common function of airflow measurement. It is advised that the Mass Air Flow Sensor be routinely maintained for the Ford Explorer to function optimally.

We provide a wide range of Ford Explorer Mass Air Flow Sensor at the best prices possible. If you need Ford Explorer Mass Air Flow Sensor, you can shop with confidence on our website. All our OEM parts come with a manufacturer's warranty and are delivered to your door step with a fast delivery service.
