Mass Air Flow Sensor: What It Does | AutoGuru

· Common mass air flow sensors use a heated platinum wire in the sensor that records an electrical resistance value in the car’s engine control module. As more air is drawn into the engine, the airflow cools the heated wire, changing the resistance value. The resistance difference is used to calculate how much air is being consumed.

How to Replace a Mass Air Flow Sensor - Advance Auto Parts

· 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. The most common signs of a failing mass air flow sensor are poor engine performance, such as hesitation or stalling; lack of power; poor fuel economy; and difficulty starting. P0101 is the most common code, but there are others, depending on …

Chevrolet Silverado 1999-2006 How to Clean or Replace Mass ...

· The mass air flow (MAF) sensor in your truck plays a vital roll in the operation of its engine. Essentially, this sensor measures the amount of air entering the engine to determine how much fuel to deliver. Even though air entering the engine passes through the air filter before reaching the MAF sensor, it can still become dirty over time or even fail completely. So if you notice the engine ...

How to Bypass the Cold Air Intake Sensor | It Still Runs

There is a sensor on the air intake called the mass air flow sensor. This sensor calculates how much air to mix with the fuel. If you are using a cold air intake, the MAF sensor might not be calculating properly. This means you are not getting the added gas mileage that most cold air intakes advertise. You can bypass the MAF sensor, and allow the O2 sensor to calculate how much air is needed ...

Mass flow sensor - Wikipedia

A mass (air) flow sensor (MAF) is a sensor used to determine the mass flow rate of air entering a fuel-injected internal combustion engine. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its density with temperature and pressure. In automotive applications, air density varies with the ambient ...

How to Troubleshoot a Mass Airflow Sensor - AxleAddict

· Question: My mass air flow sensor on an 88 Camaro reads 5-volt reference between signal and ground while running and unplugged, on the ECM side, at idle. Shouldn't the mass air flow sensor dictate the voltage going out to the ECM? While plugged in, there is erratic non-detectable voltage, on/off, on/off. My ground tests good, and I have excellent battery voltage on ECM side of the …

Measuring Air Flow -

· The mass air flow (MAF) sensor in an automobile converts the amount of air drawn into the engine into a voltage signal to calculate engine load. This is necessary to determine how much fuel to inject, when to ignite the cylinder, and when to shift the transmission. The air flow sensor is located directly in the intake air stream, between the air cleaner and throttle body where it can measure ...
