The most common symptoms of a malfunctioning MAS sensor include. The mass air flow MAF sensor part of your vehicles electronic fuel injection system is responsible for calculating the total amount of air entering the engine. How the MAF Works.

A faulty mass airflow sensor will cause problems similar to low compression or low vacuum and will also show symptoms similar to when your vehicle has low fuel pressure from a faulty fuel pump. In most cases false air leaks will cause low. They use a MAP sensor not a MAF sensor.

92 Ford Mustang GT. Before we jump into the diagnostic lets take a look at how the MAF sensor works so the procedure makes sense to you. Faulty Mass Airflow Sensor Symptoms.

Symptoms of a bad mass air flow sensor A contaminated or failed mass air flow sensor cannot measure the amount of air flow correctly. 2001 CHEVY SILVERADO 2500 HD. The Mass Airflow Sensor MAF measures the amount of air entering the engine and the Engine Control Module ECM uses the information to determine the proper amount of fuel quantity and ignition timing.

Here are some of the most common symptoms of a faulty mass airflow sensor. Basically the MAF sensor measures the amount of air flowing into the engine through the air cleaner assembly which contains the air filter and connects to the throttle body. Since the AFM has two basic functions that of measuring air flow as well as turning on the fuel pump problems can arise in these two areas.

A Bad MAF sensor can lead to poor driving experiences such as engine stalling and jerking or hesitation when you accelerate. Since this sensor measures the actual amount of air entering the motor when it fails the engine control module ECM takes the wrong information and delivers incorrect volumes of fuel to the cylinders. This last symptom is probably the most obvious because you already know that a faulty MAF sensor is causing a faulty air-fuel mixture.

Signs of a bad MAS sensor may mimic problems such as low vacuum low compression or low fuel pressure due to a bad fuel pump. The engine is hard to start or has trouble turning over. An improperly installed or collapsed air filter can cause the air flow sensor to fail sooner.
