How to Replace a Mass Air Flow Sensor

2019-01-15· Like any other engine sensor, the mass air flow sensor can fail over time. Just like with a headlight light bulb, thousands of hours at operating temperature degrades the internal components. The mass air flow sensor can also get dirty if the engine air filter is not changed on time, which results in the same symptoms as a failed sensor.

Failure in Spec: What Happens When a Mass Airflow Sensor ...

Digital sensors work basically the same way, but instead of reporting the current flow as a voltage signal, the sensor reports the duty cycle of the voltage flowing through the hot wire (that’s how current is controlled). On MAF sensors from the 1980s and early 1990s, the duty cycle generally tops out at about 160 Hz, but on more modern sensors the duty cycle is in the kilo-hertz range ...

Part 1 -How to Test the Ford Mass Air Flow (MAF) Sensor

2011-03-14· 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. 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 …

Mass Air Flow Sensors: Everything to Know ...

2016-07-25· Your vehicle’s mass air flow sensor (also called “MAF”) works by heating up a thin wire to check the volume of air entering the engine. On the other side, your vehicle’s computer calculates the electrical resistance by seeing how long it takes for the passing air to cool down that same wire. And with this complete picture of air flow, the computer can tell the fuel injectors how much ...
