Make sure that in the initial position, the top edge of the air flow meter pressure disk is at the same level with the base of the cone of the air flow meter body or no more than 5 mm below it.
If necessary, adjust the position of the pressure plate of the air mass meter by bending the spring clip.
Check the installation of the pressure disc by placing a 0.10 mm spacer at four points around the circumference.
If the position of the pressure disk is incorrect, loosen the set screw 3, center the pressure disk and then tighten the screw 3 to a torque of 0.5 kgf·m.
