Alpine MAF sensor clean
Does My Alpine Need a MAF Sensor Clean?
A Alpine MAF sensor is situated between the air filter and the intake manifold and uses wires to determine how much air is flowing. It does this by reading how much energy is required to keep one of the wires hot, as air passes. When the Alpine engine is idling there is less airflow so less energy is needed to keep the wire hot and when there is high airflow, more energy is used to maintain heat in the wire.
If the Alpine MAF sensor fails and it can’t measure the airflow correctly, the incorrect amount of fuel will be delivered to the injectors. As shown above, this can impact the drivability of the Alpine and long term can cause engine damage. Alpine engines don’t like to run lean or rich. It’s good to practise to have the MAF sensor cleaned as part of regular maintenance or when issues arise, for reliability, performance and Alpine engine longevity.
The cost to clean a MAF sensor will depend on the location of the sensor in the Alpine and how long the job takes, it might cost around $40 - $100 and if the sensor is damaged or faulty you will need to get it replaced, which will be an additional cost.
