What is a bad mass air flow sensor?

What is a bad mass air flow sensor?

An MAF, or Mass Air Flow, sensor is a device used to measure the density of air flowing into the engine. The MAF sensor can go bad for numerous reasons, resulting in symptoms a car operator can use to help determine and resolve the problem. A lit “Check Engine” light is an early symptom of an MAF sensor going bad.

How much does mass air flow sensor replacement cost?

Replacement Cost. The replacement cost of a mass air flow sensor is anywhere from $225 to $370. The cost of the part alone is about $200 to $300 while the labor cost is around $25 to $70.

What happens when a mass air flow sensor goes bad?

A bad mass air flow sensor won’t 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 . 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.

What are the symptoms of a bad mass air sensor?

The most common symptoms from a bad mass air flow sensor are slow accelerating and reduced engine power. You can also notice a difference in the fuel economy as the main function of the mass air flow sensor is to let the engine know how much fuel it should inject.

What causes a mass air flow sensor to go bad?

The mass air flow sensor is prone to failure due to age or other factors affecting its performance. Common pollutants like dirt and dust are the major reason behind a failing air flow sensor.

What are the symptons of a malfunctioning mass airflow sensor?

Check Engine Light. The most reliable early symptom of a failing or failed MAF is the illumination of the check engine light on the instrument panel.

  • or you can do it yourself using a digital auto diagnostics scanner.
  • Performance.
  • Particle Buildup.
  • Cleaning.

    What are symptoms of a defective mass air flow sensor?

    Symptoms of A Bad Mass Air Flow Sensor Check Engine Light appearing on the dashboard. A bad mass air flow sensor will usually trigger a check engine light. An engine that is difficult to start. Since the ECU can’t measure incoming air mass, it needs to compensate for this lack of information using the rest of the Poor fuel economy. Rough Engine Idle. Engine hesitation during acceleration.
