TROUBLESHOOTING HINTS
If the waste gate solenoid is not on then full boost pressure will be routed to the waste gate limiting power and causing a noticeable loss of acceleration.

WASTE GATE SOLENOID INSPECTION

1. Operation check
Using a hand vaccum pump, apply a negative pressure to the solenoid valve nipple on which the white vacuum hose is connected, and check air-tightness when the Voltage is applied to the solenoid valve terminal and when it is released from the terminal.





2. Continuity check of coil
Measure the solenoid valve terminal resistance.

Standard value: 36 - 44 Ohms [at 20°C (68°F)]
