3. If there is a significant deviation from the standard value,
check the actuator or the waste gate valve: replace
actuator or turbocharger assembly if necessary.
WASTE GATE SOLENOID VALVE CHECK
OPERATION CHECK
1. Connect a hand vacuum pump to the solenoid valve nipple
A.
2. Using a jumper wire, connect between the solenoid valve
terminal and battery terminal.
3. Connecting and disconnecting the jumper wire at the
battery negative terminal to apply a negative pressure,
check tightness.

AIR BYPASS VALVE CHECK
1. Remove the air bypass valve.
2. Connect the hand vacuum pump to the nipple of the
air bypass valve.
3. Apply a negative pressure of approximately 49 kPa, and
check that air tightness is maintained.

A nipple.
4. Connect the solenoid valve terminal and battery terminal
with a jumper wire.
5. Disconnect the jumper wire between the battery’s ( - )
terminals, apply a negative pressure, and inspect the
tightness.
