    Does anyone have instructions on how to remove, clean, then reinstall the MAF sensor for a 1999 Tacoma 4x4 2.7L 3RZ-FE 5-speed. I heard you have to do this very carefully. I'm getting a CEL (P0420) randomly and I want to clean this area good and then see if I need to replace it or not. I have already replaced the O2's and checked the exhaust and done all other maintenance.

    Thanks,
    Corey

    It's just two screws at the intake tube coming out of the air box. They are loctited in so it will take some pressure to get them out. Just disconnect the NEG battery cable, then the sensor plug, remove the 2 screws and it's out. Just be careful spraying it and only use MAF or Electronic contact clear. NOTHING ELSE.

    Thanks Ben, I figured it couldn't be too difficult. So I should just spray it down and let it dry only? No rubbing?

    YES, just spray it. Do not, for the love of God, touch it. Spary it, let it dry (evaporates pretty quick), spray it, dry, spray, dry...............etc. You get the picture.

    Spray liberally and let dry, pretty simple.
