Do this with your car and save 30% on your fuel consumption (Page 3 ) | April 25, 2025

It’s difficult to give an exact figure, as it depends on the condition of your sensor and your vehicle. However, here’s a general estimate:

• MAF Sensor Cleaning  : Can reduce your fuel consumption by  5-20% .
• Replacing a faulty sensor  : Can provide savings of  10-30% .

On average, a French driver spends around  1,500 euros per year on fuel . A 20% saving   therefore represents around  300 euros per year .

How to repair or replace a MAF sensor?

If you think your MAF sensor is the problem, here’s what to do:

• Cleaning  : Use only a  specific MAF sensor cleaner . Never use  WD-40 or carburetor cleaner , which can damage the sensor.
• Replacement  : If the sensor is too damaged, replace it. The cost generally ranges from  30 to 150 euros  depending on the model.
• Diagnosis with an OBD2 scanner  : Look for error codes like  P0101, P0102 or P0103  to confirm the problem.

A faulty MAF sensor can  seriously affect  your car’s fuel consumption. Fortunately, a simple cleaning or replacement can save you  up to 30% on fuel . If you notice a loss of power, black smoke, or excessive fuel consumption, it’s time to check this sensor.  Don’t let this small component hurt your fuel budget.
