TURBOCHARGER WASTEGATE ACTUATOR CHECK

1.Connect a hand vacuum pump (pressure-application type) to nipple. caution In order to abovid damage to the diaphragm, do not apply a pressure of 94 kPa (13.6 psi) or higher. 2.While gradually applying pressure, check the pressure that begins to activate (approximately 1 mm stroke) the turbocharger wastegate actuator rod. Standard value: 78 - 82 kPa (11.4 - 11.8 psi) 3.If there is a significant deviation from the standard value, check the actuator or the turbocharger wastegate regulating valve: replace if necessary.
