It is on the side of the intake going into the throttle body.
1. Pull up or squeeze the red retainer clip and unplg the wire.
2. Remove two torx screws and pull out the unit.
3. Spray the little wires with MAF or Electronic cleaner, available at auto parts stores.
4. let air dry for a couple of minutes. DO NOT TOUCH THE LITTLE WIRES!
5. Reverse to install.
Takes about 5 minutes. I think the spray cleaner was about $10 and will last forever.
