Turbocharger WASTEGATE Actuator Check

  1. Connect a hand vacuum pump (pressure-application type) to nipple.
    CAUTION: In order to avoid damage to the diaphragm, do not apply a pressure of 117 kPa (17 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: 98 - 102 kPa (14.3 - 14.7 psi) 

  3. If there is a significant deviation from the standard value, check the actuator or the turbocharger wastegate regulating valve: replace if necessary.
