PRECAUTION
1. MAINTENANCE PRECAUTION
(a) Do not stop the engine immediately after pulling a trailer,
or after driving at a high speed, or uphill drive. Let the en-
gine Idle for 20 to 120 seconds before turn the ignition
switch OFF (According as the driving condition, the idling
time varies).
(b) Avoid quick acceleration or quickly accelerating the en-
gine RPM immediately after the starting a cold engine.
(c) If the turbocharger is found to be defective, it must be re-
placed. Also, inspect a source of the trouble including
conditions of the turbocharger that having been used. Re-
pair or replace the followings as necessary:
(1) Engine oil (Level and quality)
(2) Oil lines leading to the turbocharger
(d) Pay due attention when removing and reinstalling the
turbocharger assembly. Do not drop, or do not give shock,
or do not grasp easily±deformed assembly parts such as
the actuator or push rod in removal and reinstallation.
(e) Before removal, cover both the intake and exhaust ports
and the oil inlet to prevent dirt or foreign objects from be-
ing introduced.
(f) If replacing the turbocharger, check for deposits in the oil
pipe. If necessary, replace the oil pipe too.
(g) Thoroughly remove old gasket sticking to the lubrication
oil pipe flange and the turbocharger oil flange.
(h) If replacing the bolt(s) or nut(s), must use Toyota genuine
parts to prevent breakage or deformation.
(i) If replacing the turbocharger, put 20 cm
3 (1.2 cu in.) of
fresh oil into the turbocharger oil inlet hole and turn the tur-
bine wheel by hand to spread oil to the bearing.
(j) If overhauling or replacing the engine, cut the fuel supply
after reassembly and crank the engine for 30 seconds to
feed oil throughout the engine then run the engine at idle
for 60 seconds.

INSPECTION
1. INSPECT INTAKE AIR CONTROL VALVE ASSY
(a) With 34.7 kPa (260 mm Hg, 10.2 in. Hg) of vacuum ap-
plied to the actuator, check that the actuator rod moves.
(b) One minute after applying the vacuum, check that the ac-
tuator rod does not return.
(c) If the operation is not as specified, replace the intake air
control valve assembly.
NOTICE:
Do not touch the adjust screw.
2. INSPECT VACUUM SWITCHING VALVE ASSY NO.1
(a) Using an ohmmeter, measure resistance between each
terminal.
Resistance: 33 to 39
at 20
C (68
F)
(b) Check that air flows form port B to the filter.
(c) Apply battery voltage across the terminals.
(d) Check that air flows from port B to port A.

1. INSPECT INTAKE AIR CONTROL SYSTEM
(a) Using a 3±way connector, connect vacuum gauge to the
actuator hose.
(b) Connect the hand±held tester to the DLC 3.
(c) Start the engine.
(d) Select the active test mode according to the message on
the hand±held tester.
Vacuum:
VSV ONApprox. 27 kPa (200 mm Hg, 7.9 in. Hg)
VSV OFF0 kPa (0 mm Hg, 0 in. Hg.)
(e) Shift the transmission into the P range and control the ac-
celerator pedal.
(f) Check the VSV operation using the hang±held tester.
HINT:
The value in the illustration is only for reference; the throttle
valve may operate diversely depend on the engine running
condition.
