Wastegate Solenoid Valve

SOLENOID TESTS

Waste Gate Solenoid Valve Location:

1. Mark and disconnect the vacuum hose (black with a white stripe) from the solenoid valve.
2. Disconnect the electrical harness connector.
3. Connect a manual vacuum pump to the fitting the white striped hose was removed from.

Solenoid Operational Test:

4. Apply a vacuum while Voltage is applied to the solenoid valve. Verify that the valve does not hold vacuum.
5. Remove power from the solenoid valve and verify that the solenoid valve holds vacuum.

Solenoid Resistance Check:

6. Measure the resistance between the two terminals of the solenoid valve, and verify that the resistance is between 36 and 44 Ohms at 20 degrees C (68 degrees F).

HARNESS TESTS
1. Disconnect the solenoid connector and turn the key to the ON position.
2. Using a volt meter, check the Voltage between solenoid harness connector terminal 2 and ground.

Voltage: System Voltage

3. Turn the key to the OFF position and disconnect the ECU harness connector.
4. Using an ohm meter, check for continuity between ECU harness connector terminal 105 and solenoid harness connector terminal 1.

Continuity: Should exist

5. Using an ohm meter, check for continuity between ECU harness connector terminal 105 and ground.

Continuity: Should not exist
