CRC Mass Air Flow Sensor Cleaner
MSRP: $9.49
Tools Required: Philips screwdriver
Cleaning the sensor is a very easy process and can extend the life of the sensor and make sure you are getting optimal fuel economy.
Locate the MAF sensor on the intake tube.
2. Remove the connector on the sensor by pressing on the tab and pulling up on the connector body, not on the wires.
3. Remove the two (2) screws holding the sensor onto the intake and pull straight out on the MAF sensor. If you cannot access the back screw, remove the clips on the intake housing and rotate it up slightly.
4. Spray 10-15 blasts in the tubes and the sensor area. (I couldn't spray the cleaner and take a picture at the same time, so these pictures are for reference only. And use gloves) Don't be shy with the spray, use very liberally and DO NOT physically touch any part of the sensor physically with anything but the spray (not the red spray tube or a towel)
5. Allow the sensor to dry for 10-15 minutes.
6. Reverse the process to reinstall the sensor. The screws should just be tightened until snug but avoid over-tightening since it is in a threaded plastic part.
7. Your rig may idle rough initially as the system "relearns" the cleaned sensor readings but this should work itself out after a few minutes.
This process is very easy and can easily be incorporated into your regular maintenance routine. Depending how much spray you use, the cleaner can be used for at least a few times and is much cheaper than a new replacement sensor.
