Mini MAF sensor clean
Does My Mini Need a MAF Sensor Clean?
A Mini 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 Mini 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 Mini 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 Mini and long term can cause engine damage. Mini 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 Mini engine longevity.
The cost to clean a MAF sensor will depend on the location of the sensor in the Mini 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.
