4. Pressurize slowly with the Mighty Vac, and check the pressure when the control rod stroke (D) becomes 1±0.15 mm (0.0394±0.0059 in). If it is not within the standard, replace the turbocharger assembly.
   CAUTION: Do not pressurize over 112.7 kPa (1.15 kg/cm² , 16.34 psi) to prevent damaging the waste gate actuator.
