WASTE GATE ACTUATOR CHECK <4G1>

M1151001200297

AK402022

1. Connect a manual pump (pressure-application 

type) to nipple.

CAUTION

In order to avoid damage to the diaphragm, do 
not apply a pressure of 75 kPa or higher.
2. While gradually applying pressure, check the 

pressure that begins to activate (approximately 1 
mm stroke) the waste gate actuator rod.

Standard value: Approximately 60 kPa

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.

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.

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 93 

kPa, and check that air tightness is maintained.

4. Also check operation of the valve.
