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.

. Youll notice if the tailpipes eject black smoke or when the engine runs rough or backfires. The mass air flow MAF sensor is an important component which the engine control unit depends on. If the engine control.

Quick test to tell if Mass Air Flow Sensor is bad or dirty which could be causing your car or truck to run bad or keep cutting off. Mass air flow sensor problems 1. As a result a bad mass air flow sensor causes various driveability problems including a no-start stalling lack of power and poor acceleration.

Other faults can cause similar codes and symptoms such as a faulty. This makes the control unit fail in. Stalling the car 4.

Mass Air flow Sensor MAF. Your mass air flow tells your cars computer information about the air that is used in your engines combustion chamber. A faulty MAF sensor can cause your vehicle to run too rich or run too lean.

Sensors are in use every time your vehicle is operating. The most common problems are. The Engine Runs Lean or Rich 2.

Up to 8 cash back A MAF sensor that continuously over-reports or under-reports airflow into the engine will cause an engine to run rich or lean. If the wire is dirty for example due to dirt oil or even. The mass air flow sensor measures the air mass flowing into the engine intake.

Measuring air mass is critical in calculating how much fuel to add to achieve the correct air. Depending on the make and model of the vehicle a MAF sensor problem could cause a variety of issues. A contaminated or failed mass air flow sensor cannot measure the amount of air flow correctly.

Signs of a bad MAF sensor may mimic problems such as low vacuum low compression or low fuel pressure due to a bad fuel. 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. The engine cranks but wont start.

A contaminated or failed mass air flow sensor cannot measure the amount of air flow correctly. A lot of manufacturers have repeated issues with sensors so this is common. The cost of replacing the mass airflow sensor depends on the model of your car your location and the labor cost of the mechanic you are using.

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. When the flow of air enters the fuel injection system of the engine the. Why Mass Air Flow Sensors Fail.

Turning over is difficult 3. 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. This causes the engine computer to miscalculate the amount of injected fuel.

What Are the Symptoms of a Faulty Mass Air Flow Sensor. 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. Often the problems associated with the mass air flow sensor occur due to dirt and debris buildup on the sensor head.

The mass airflow sensor commonly abbreviated to MAF is one of the most important engine management sensors. Mass airflow sensor cost to replace. A bad mass airflow sensor can leave your Chevy.

If your Check Engine light is on due to mass air flow sensor issues it first needs to be confirmed by a qualified mechanic. This causes the engine computer to miscalculate the amount of injected fuel. Youll find that these.

This particle accumulation over time results in poor. As a result a bad mass air flow sensor causes various driveability problems including a no-start stalling lack of power and poor accelerationA problem with the air flow sensor could also.
