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

The sensor works by heating a delicate platinum wire or plate and measuring the current required to go on information technology at a constant temperature while air blows by it. Over time, dust and oil particles stick to the hot wire/plate and broil on. Eventually, those baked-on particles insulate the wire/plate from the airstream. This causes starting, idling and dispatch 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 yous make clean your car's MAF sensor regularly, yous can avoid that $300 repair and go along your engine running at top efficiency. The mass air flow cleaner only costs almost $7! We recommend that yous clean the MAF sensor every time yous change your air filter. Here's how:

Earlier going to the store, pull off the air duct betwixt the air filter box and the throttle body to come across 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 employ any other cleaners; they can ruin the MAF. Everything you lot demand is available at CarQuest, Advance and O'Reilly auto parts stores.

With the mass air flow cleaner and tools in hand, locate the MAF sensor in the air duct betwixt the air filter box and the throttle body. Earlier you remove the sensor, use a camera to tape the sensor setup and connections for reference afterwards. Carefully remove the sensor from the air duct and disconnect the electrical connector.

Spray 10 to xv spurts of the mass air bloom cleaner onto the wire or plate. Don't scrub the parts; you may break the wire or damage the plate. Allow the MAF sensor to dry completely before reinstalling it in the air duct.
