What Is A Mass Air Flow Sensor?
There are two independent types MAF sensors- hot wire and cold wire. A hot cable MAF detector uses a platinum wire located in the path of atmosphere hang, which is heated using specific voltage. As the air travel passes over the hot wire, it is cooled, decreasing the wire ’ s resistance to voltage. The engine control module ( ECM ) measures this change and alters the tune accordingly. The other type is a cold wire detector. These are normally found in GM engines. These sensors use both a hot electrify and a cold wire, where the cold wire functions as a reference for the hot telegram .
Because these sensors are directly exposed to the air, they pick up contaminants that alter their readings, which lead to rough run conditions. You can ’ thymine use carburetor or bracken cleaners on a MAF detector, as the chemicals in those cleaners can destroy the finespun sensors. rather, a special MAF detector clean is required. CRC MAF Sensor Cleaner is specifically designed to remove oil, scandal, fibers and dust from the detector without damage. The chemicals used are hexane-based, which evaporate cursorily without the use of alcohol. A clean MAF detector is a happy MAF detector. The process is quite simple and can be completed in approximately 10 minutes.
How To Clean A Mass Air Flow Sensor
first, NEVER use MAF detector clean with the engine run or even with the keystone in the operate position. This can cause major price to the detector. With the key off, unplug the detector .
future, remove the atmosphere intake tube and then remove the MAF detector .
place the MAF detector on a towel to catch the runoff. Insert the fictile chaff into the nozzle on the can and spray the inner of the house with 10-15 blasts. You need to cover the hot wire ( south ) and plate. Be very careful to not touch the wires with any object, including the chaff. The wires are quite delicate.

Spray all sides of the detector and house, including the connectors .
Reinstall the detector into the cable car and allow a few minutes for the chemicals to evaporate before starting the engine .
It is a good idea to clean the MAF detector every time you change or clean the air out filter. A clean MAF detector can restore 4-10 horsepower to the wheels, which is a meaning numeral for merely cleaning a detector. Warning: Do NOT use any MAF detector cleaners on Karman-Vortex style air flow sensors, which are typically found in Toyota Supra turbos, Mitsubishi ( including the DSM rebadged Eagle Talon and Plymouth Laser ), and most Lexus engines. These special Karman-Vortex sensors use highly sensitive components that can not be cleaned and any attempt to do then may cause serious damage to the MAF detector. There is no dependable method acting for a DIYer to clean a Karman-Vortex style air flow detector. When in doubt, just leave it alone.
