Switch off the engine though turning the key in the ignition off then remove the electrical connector of the MAF sensor. Thirdly, remove bolts and nuts and then unbolt the hose clamp on both ends of the air intake duct and take off the air intake duct along with the MAF sensor. Next, every hose clamp screw installed at the both ends of the MAF sensor needs to be unscrewed and MAF sensor has to be taken off the system. To install, reverse all screw and bolt procedures withMuch care, especially to tighten the MAF sensor and air intake duct hose clamp screws.
