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 .
