This involves a lot of time and is quite inefficient compared to just reading the MAF yourself. The reason is that the ECU will always have to perform “calculations” to make sure it gets the right amount of air and fuel to inject into the engine. If you drive without the plugging of your MAF sensor, you’ll have poor gas mileage. If your MAF sensor is unplugged your engine is unlikely to get damaged so you shouldn’t worry about that but there are side effects of driving without plugging the airflow meter sensor including: Poor Gas Mileage: What will happen if you drive with a Mass Airflow Meter Sensor unplugged? This may also cause permanent damage to the engine computer and/or oxygen sensor. May also cause vehicles to fail emissions tests (if the state requires monitoring of MAF). The vehicle may require more frequent service intervals than indicated by the manufacturer. You need to be aware that the car is not designed with no airflow meter, so it will run unsatisfactory. But you will lose the airflow information and will have a hard time maintaining the correct fuel ratio. Can you drive with the Mass Airflow Sensor Unplugged?
The actual design, construction, and method of operation of a MAF sensor vary considerably but all have the same purpose. It works by measuring the mass of air that flows past it and using this to calculate the actual flow rate.
