How a faulty MAF sensor can increase your fuel consumption

Imagine trying to prepare a recipe by adding too much salt. The dish becomes inedible. Similarly, a faulty MAF sensor sends incorrect information to the ECU. This can cause:

• Increased fuel consumption  :  Up to 20 to 30%  in the event of a severe malfunction.
• A loss of power  : Your vehicle seems to lack power, even when simply accelerating.
• The appearance of black smoke from the exhaust  : Sign of a fuel mixture that is too rich.
• Jerking or Rough Idling  : The engine has difficulty running smoothly.

A faulty sensor can therefore  significantly increase your fuel consumption .

Concrete cases that prove the effectiveness of the repair

To illustrate the impact of a faulty MAF sensor, here are some concrete examples:

• 2012 Toyota Corolla  : Its consumption had increased to  12 L/100 km  due to a dirty MAF sensor. After cleaning, it dropped to  8.5 L/100 km , a reduction of  29% .
• 2015 Ford Focus  : Victim of a loss of power and excessive consumption, it went from  10.5 L/100 km  to  8.2 L/100 km  after replacing the sensor, a  22%  saving.
• 2010 Honda Civic  : With rough idling and excessive fuel consumption, it reduced its fuel consumption by  15%  after cleaning the sensor.

These examples show that a simple maintenance or replacement can  really make a difference to your fuel budget .
