What is a Mass Air Catamenia (MAF) sensor? A MAF sensor monitors the temperature and weight of air entering your engine. Your onboard reckoner needs that information to calculate the right corporeality of fuel for all engine operating weather condition.

The sensor works past heating a delicate platinum wire or plate and measuring the current required to keep it at a constant temperature while air blows past it. Over time, dust and oil particles stick to the hot wire/plate and bake on. Eventually, those baked-on particles insulate the wire/plate from the airstream. This causes starting, idling and acceleration problems, as well as poor gas mileage.

Carmakers like Ford and Chevrolet recommend that you replace the MAF sensor ($300) at that point. But if y'all make clean your car's MAF sensor regularly, you lot can avert that $300 repair and continue your engine running at summit efficiency. The mass air menses cleaner just costs almost $7! We recommend that y'all clean the MAF sensor every fourth dimension you lot change your air filter. Here's how:

Earlier going to the store, pull off the air duct between the air filter box and the throttle torso to see how the MAF sensor is anchored. If yous encounter Torx screws, buy a Torx tool and a can of CRC Mass Air Flow Sensor Cleaner. Don't use whatsoever other cleaners; they can ruin the MAF. Everything you need is available at CarQuest, Advance and O'Reilly car parts stores.

With the mass air period cleaner and tools in manus, locate the MAF sensor in the air duct between the air filter box and the throttle torso. Earlier you lot remove the sensor, use a camera to record the sensor setup and connections for reference later. Carefully remove the sensor from the air duct and disconnect the electrical connector.

Spray 10 to fifteen spurts of the mass air bloom cleaner onto the wire or plate. Don't scrub the parts; y'all may interruption the wire or damage the plate. Permit the MAF sensor to dry completely before reinstalling it in the air duct.
