(d) If you have no TOYOTA Hand±Held Tester:
Forced driving of the VSV for the EVAP.
(1) Disconnect the VSV connector for the EVAP.
(2) Connect the positive (+) and negative (±) leads from
the battery to the VSV terminals for the EVAP.
(3) Start the engine.
(e) Check the vacuum at idle.
Vacuum:
Maintain at 0.368 ± 19.713 in.Hg (5 ± 268 in.Aq) for over
5 seconds
HINT:
If the vacuum does not change, you can conclude that the hose
connecting the VSV to the service port has come loose or is
blocked, or the VSV is malfunctioning.
(f) TOYOTA Hand±Held Tester:
Conclude forced driving of the VSV for the EVAP.
(1) Stop the engine.
(2) Disconnect the TOYOTA hand±held tester from the
DLC3.
(g) If you have no TOYOTA Hand±Held Tester:
Conclude forced driving of the VSV for the EVAP.
(1) Stop the engine.
(2) Disconnect the positive (+) and negative (±) leads
from the battery from the VSV terminals for the
EVAP.
(3) Connect the VSV connector for the EVAP.
(h) Disconnect the vacuum gauge from the EVAP service
port on the purge line.
(i) Connect a pressure gauge to the EVAP service port on
the purge line.
(j) Check the pressure.
(1) Close off the air drain hose at the marked position
of the canister with a hose clipper or similar instru-
ment.

HC complies with regulations.
1. INITIAL CONDITIONS
(a) Engine at normal operating temperature
(b) Air cleaner installed
(c) All pipes and hoses of air induction system connected
(d) All accessories switched OFF
(e) All vacuum lines properly connected

CONDS

40 cm (1.3 ft) INTO TAILPIPE DURING IDLING
5. IMMEDIATELY CHECK CO/HC CONCENTRATION AT
IDLE AND/OR 2,500 RPM

When performing the 2 mode (2,500 rpm and idle) test, follow
the measurement order prescribed by the applicable local regu-
lations.

If the CO/HC concentration does not comply with regulations,
troubleshoot in the order given below.
(1) Check oxygen sensor operation.
(See page DI±66)
(2) See the table below for possible causes, then in-
spect and correct the applicable causes if neces-
sary.

COMPRESSION
INSPECTION
HINT:
If there is lack of power, excessive oil consumption or poor fuel
economy, measure the compression pressure.
1. WARM UP AND STOP ENGINE
Allow the engine to warm up to normal operating temperature.
2. DISCONNECT IGNITION COIL CONNECTORS
3. REMOVE SPARK PLUGS (See page IG±1)
4. INSPECT CYLINDER COMPRESSION PRESSURE
(a) Insert a compression gauge into the spark plug hole.
(b) Fully open the throttle.
(c) While cranking the engine, measure the compression
pressure.
HINT:
Always use a fully charged battery to obtain engine speed of
250 rpm or more.
(d) Repeat steps (a) through (c) for each cylinder.
NOTICE:
This measurement must be done in as short a time as pos-
sible.
Compression pressure:
1,226 kPa (12.5 kgf/cm
2, 178 psi) or more
Minimum pressure: 981 kPa (10.0 kgf/cm
2, 142 psi)
Difference between each cylinder:
98 kPa (1.0 kgf/cm
2, 14 psi) or less
(e) If the cylinder compression in one or more cylinders is low,
pour a small amount of engine oil into the cylinder through
the spark plug hole and repeat steps (a) through (c) for
cylinders with low compression.

If adding oil helps the compression, it is likely that
the piston rings and/or cylinder bore are worn or
damaged.

If pressure stays low, a valve may be sticking or
seating is improper, or there may be leakage past
the gasket.
5. REINSTALL SPARK PLUGS (See page IG±1)

VALVE CLEARANCE
INSPECTION
HINT:
Inspect and adjust the valve clearance when the engine is cold.
1. REMOVE CYLINDER HEAD COVER
(a) Disconnect the 4 high±tension cords from the clamps on
the cylinder head cover.
(b) Disconnect the 4 high±tension cords from the spark
plugs.
(c) Disconnect the PCV hose from the intake manifold.
(d) Disconnect the PCV hose from the cylinder head cover.
(e) Disconnect the engine wire clamp from the mounting bolt
of the No.2 timing belt cover.
(f) Remove the cylinder head cover. (See page EM±33)
2. SET NO.1 CYLINDER TO TDC/COMPRESSION
(a) Turn the crankshaft pulley, and align its groove with timing
mark º0º of the No.1 timing belt cover.
(b) Check that the valve lifters on the No.1 cylinder are loose
and valve lifters on the No.4 are tight.
If not, turn the crankshaft one revolution (360°) and align the
mark as above.
3. INSPECT VALVE CLEARANCE
(a) Check only the valves indicated.
(1) Using a feeler gauge, measure the clearance be-
tween the valve lifter and camshaft.
(2) Record the out±of±specification valve clearance
measurements. They will be used later to determine
the required replacement adjusting shim.
Valve clearance (Cold):
Intake0.19 ± 0.29 mm (0.007 ± 0.011 in.)
Exhaust0.28 ± 0.38 mm (0.011 ± 0.015 in.)
(b) Turn the crankshaft one revolution (360°) and align the

position shown in the illustration.
(4) Remove the adjusting shim with a small screwdriver
and magnetic finger.
(b) Determine the replacement adjusting shim size by follow-
ing the Formula or Charts:
(1) Using a micrometer, measure the thickness of the
removed shim.
(2) Calculate the thickness of a new shim so that the
valve clearance comes within specified value.
T ........... Thickness of removed shim
A ........... Measured valve clearance
N ........... Thickness of new shim
