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 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.

2. Connect the pressurized type hand vacuum pump with the
three-way joint.
3. Use the turbocharger wastegate actuator control boost
nipple of air outlet fitting to remove the boost hose. Plug this
nipple.
CAUTION
Do not apply the pressure of 117 kPa or more to prevent
the diaphragm damage.
4. Blocking or releasing the boost hose end, apply the
