Faulty mass air flow sensor used

Mass airflow sensor problems can cause a variety of symptoms from the annoying to the must repair. We'll discuss these in-depth on this page. MAF, is a tool found in modern engines used to monitor the incoming air. This information is essential for the engine control unit (ECU) to deliver a balanced amount of fuel mass to the engine.

Automotive Service: Inspection, Maintenance, Repair (4th ed.). Cengage Learning. The faulty mass airflow sensor and how to fix the problem written by: nandy A vehicles MAF or mass airflow sensor, is the element that measures the density and flow of the air passing in to the combustion section.It assists the vehicles computer activate the air ratio to fuel.

The MAF sensor uses a heated wire or filament to measure airflow into the engine. This is vital information for controlling the fuel mixture. Mass Air Flow (MAF) Sensor. This test is almost but not exactly the same for all types of MAF Sensors. MAP sensor signal is also used by the PCM to calculate the fuel requirements and is based on what is called the speed-density method of calculating engine load. This engine load calculation is what makes the accuracy of the MAP sensor signal so critical.The MAF sensor used on this engine is a hot wire type.

This engine uses the MAF sensor in order to measure air flow rate.

How to tell you got a bad MAF

Thermistors are used in MAF sensors to measure the transfer of heat from the thermistor to the air passing by the sensor. A thermistor's resistance changes as its surrounding temperature changes.
