EG-159
ENGINE – TURBOCHARGER SYSTEM (2JZ–GTE)
5. INSPECT EXHAUST BYPASS VALVE OPERATION
(a) Plug one side of the actuator air hose end.
(b) Using SST, apply approx. 98 kPa (1.00 kgf/cm2, 14.2 psi) of pressure to the actuator.
SST 09992–00241
(c) Move the actuator push rod, and check that the exhaust bypass valve is open.
If operation is not as specified, replace the No.2 turbocharger assembly.
NOTICE: Never apply more than 187 kPa (1.91 kgf/cm2, 27.2 psi) of pressure to the actuator.
(d) Remove the plug from the actuator air hose end.
Intake Air Control Valve
INSPECT CONTROL VALVE OPERATION
(a) Using SST, apply approx. 49 kPa (0.50 kgf/cm2, 7.1 psi) of pressure to the actuator.
SST 09992–00241
(b) Move the actuator push rod, and check that the control valve is open.
If operation is not as specified, replace the control valve assembly.
Exhaust Gas Control Valve
INSPECT CONTROL VALVE FOR DAMAGE
Move the actuator push rod and control valve, and check the control valve for damage.
If the valve is damaged, replace the control valve assembly.
Air Bypass Valve
INSPECT AIR BYPASS VALVE OPERATION
(a) Check that air does not flow from port A to B.
(b) Apply vacuum to the actuator.
(c) Check that air flows from port A to B.
If operation is not as specified, replace the valve.
