Faulty mass air flow maf sensor range

There are a number of things on a car that are built to regulate the amount of air and fuel that get mixed. The mass airflow sensor is one of the most important of these sensors due to the job that it performs.

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.

MAF sensor may be hard to start or stall after starting. It may hesitate under loa surge, idle rough or run excessively rich or lean.

The mass airflow sensor (MAF) measures the amount of air entering the engine. The OBD-II code P01is set when the signal from the mass air flow sensor is out of expected range, or in other words, the MAF sensor doesn't work properly.

How to tell you got a bad MAF

The signal voltage reads anywhere from - volts which is ok from my experience.

The mass air flow sensor (MAF) is located inside the engine compartment and is used to measure the amount and temperature of air that is entering the engine at any one time. Older style meters used on fuel injection systems in the 1980s measured air volumetric flow, which worked fine but then you also needed a separate sensor to figure out how cold or dense the air was.

The main purpose of the Mass Air Flow (MAF) Sensor is to measure the volume and density of air entering the engine at any given time. The computer uses this information in conjunction with input from other sensors, to calculate the correct amount of fuel to deliver to the engine.

The Mass AirFlow (MAF) sensor is usually located between the air filter housing and the throttle. The MAF sensor uses a heated wire or filament to measure airflow into the engine.
