Intake Charge Pressure Control System Check
- Removing the black hose from the No. 1 turbocharger wastegate solenoid or the brown connector, connect three-way joint between the hose and the solenoid.
- Connect the pressurized type hand vacuum pump with the three-way joint.
- 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.
- Blocking or releasing the boost hose end, apply the pressure. Check the pressurized state.ENGINE STATE REFERENCE
Engine state Boost hose end Normal state Stopped: Ignition switch in "ON" position Opened Pressure leaks Closed Pressure maintained Rapid racing Pressure leaks - Put the ignition switch in "LOCK" (OFF) position.
- Disconnect the connector of No. 1 turbocharger wastegate solenoid or the brown connector.
- Blocking or releasing the boost hose end, apply the pressure. Check the pressurized state. Plug the boost hose end while driving.ENGINE STATE REFERENCE
