How to clean a MAF sensor

Best way to clean a MAF sensor

They say it can’t be done. But at $300 a pop for a new MAF sensor, you’ve got only $6 to lose by attempting to clean the old MAF sensor. Pick up a can of CRC MAF Sensor Spray Cleaner at any auto parts store or on amazon.com

1Then locate the MAF sensor. It’s between the air filter box and the throttle body.

2Disconnect the sensor from the duct.

3Then disconnect the electrical connector.

4 Locate the small circular opening inside the MAF sensor. That houses and protects the hot wire element and the thermistor that measures ambient air temperature. Spray 15 squirts of MAF sensor cleaner directly onto the wires and thermistor but DO NOT TOUCH them. They are very fragile (read break easily). Prevent the cleaner from getting into the electrical connector. Then allow the cleaner to dry for about 15 minutes and reinstall.
