Wastegate Solenoid: Testing and Inspection
Waste Gate Solenoid
Wastegate Solenoid Circuit
To test the operation of the wastegate solenoid, proceed as follows.
SOLENOID TEST
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 nipple the white striped hose was removed from.
Solenoid Operational Test
4. Attempt to 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).
