Wastegate Solenoid: Testing and Inspection

1. Remove the No.4 air cleaner pipe with No.1 and No.2 air cleaner hoses.

Removing Air Cleaner Pipe:

2. Disconnect the air inlet hoses and the air flow meter connector.

Disconnecting Air Hoses:

3. Loosen clamps and remove the mounting bolt along with the No.7 air cleaner hose and air flow meter/air cleaner cap assembly.

Removing Airflow Meter With Air Cleaner Hose:

4. Disconnect the power steering idle-up air hose.
5. Disconnect Wastegate Actuator pressure hose.
6. Using a turbocharger pressure gauge and pump, apply approximately 7.4 PSI (51 kPa) of pressure to the Wastegate Actuator.

CAUTION: DO NOT apply more than 11.4 PSI (78 kPa) of pressure to the Wastegate Actuator or damage to the actuator diaphragm could result.

Testing Wastegate Actuator With Pressure Pump:

7. Check that the actuator rod moves as pressure is applied.
8. If the actuator does not hold pressure, the diaphragm is bad. Replace the Wastegate Actuator.
9. If excessive pressure is needed to move the rod, check for a bent actuator rod or sticking Wastegate Valve.
10. Remove pressure gauge from Wastegate Actuator.
11. Reinstall PS idle-up air hose and air flow meter/air cleaner cap assembly.
12. Reconnect all air cleaner hoses and tighten clamps.
