Other faults can cause similar codes and symptoms such as a faulty oxygen sensor or a vacuum leak.

. As a result a bad mass air flow sensor causes various driveability problems including a no-start stalling lack of power and poor acceleration. How to Remove the MAF Sensor andor Housing 1. A bad mass air flow sensor wont reliably measure the amount of air coming in through the air filter resulting in a delay in the fuel delivery during sudden acceleration and a temporary lack of power.

This causes the engine computer to miscalculate the amount of injected fuel causing additional damage to your engine. The mass air flow sensor measures the air mass flowing into the engine intake. The Engine Runs Lean or Rich 2.

The ideal AFR is 1471 147 pounds of air to. Youll notice if the tailpipes eject black smoke or when the engine runs rough or backfires. Mass Air flow Sensor MAF.

The mass airflow sensor commonly abbreviated to MAF is one of the most important engine management sensors. A bad mass air flow sensor is not able to perform its task accurately resulting in a faulty reading in the amount of air entering the engine. The engine is very hard to start or turn over.

Mass Air Flow Sensor May Fail on Volkswagen Beetle Problem Description The mass air flow MAF sensor may fail resulting in drivability issues andor illumination of the Check Engine Light. Mass air flow sensor problems 1. The Symptoms of a Bad Mass Air Flow Sensor - AutoZone Signs that You Have a Failing Mass Air Flow Sensor.

A contaminated or failed mass air flow sensor cannot measure the amount of air flow correctly. Here are some of the most common symptoms of a faulty mass airflow sensor. Measuring air mass is critical in calculating how much fuel to add to achieve the correct air-fuel ratio AFR.

In such a scenario the ECU will sense the drop in engine vacuum first and then using other sensors will decide if more fuel is required. In this article we will look at what happens when you disconnect the mass airflow sensor. INFINITI I30 Vehicles With This Problem - RepairPal.

This makes the control unit fail in accurately measuring the amount of fuel needed in the engine. Also its possible that the MAF sensor is just dirty. An important role in the proper functioning of the mass air flow sensor is the air filter of the car.

Mass Air flow Sensor MAF. The MAF sensor is a part that generally lasts throughout the lifespan. A MAF sensor measures the density of the air entering the intake manifold.

By Ed Ruelas on January 08 2016 Vehicle Engine Mechanical Inspection Cost 000 Upfront Transparent Price 4. If your Check Engine light is on due to mass air flow sensor issues it first needs to be confirmed by a qualified mechanic. 7 Symptoms of a Bad Mass Air Flow Sensor This is the second one I have owned and both have had this problem.

Turning over is difficult 3. Your car has a lot of sensors and this is just one that helps your car run properly. 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.

Stalling jerking or hesitation during acceleration. The mass airflow sensor is a key sensor in your car. There are 3 key signs that may indicate its time to examine your MAF sensor.

The main cause of mass air flow failure is dust. In time the dust is deposited on the wire or the sensors circuit so it loses its sensitivity or the electronic circuit fails. A mass air flow sensor failure can cause this problem because the engine is configured to not start until the right amount of air and fuel that the engine needs to ignite can be detected.

This causes the engine computer to miscalculate the amount of injected fuel. 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. Stalling the car 4.

Since the MAF plays a critical role in managing your powertrain any problems from it will give noticeable engine problems. The amount of current going through the wire to sustain the temperature is proportional to air flow. Here are the most common issues to look out for.
