AVENSIS REPAIR MANUAL (RM1018E)
ON±VEHICLE INSPECTION
1. INSPECT INTAKE AIR SYSTEM
(a) Check for leakage or clogging between the air cleaner
housing and turbocharger inlet and between the turbo-
charger outlet and cylinder head.
(1) Clogged air cleaner...Clean or replace element
(2) Hoses collapsed or deformed...Repair or replace
(3) Leakage from connections...Check each connec-tion and repair
(4) Cracks in components...Check and replace
2. INSPECT EXHAUST SYSTEM
(a) Check for leakage or clogging between the cylinder head
and turbocharger inlet and between the turbocharger out-
let and exhaust pipe.
(1) Deformed components...Repair or replace
(2) Foreign material in passages...Remove
(3) Leakage from components...Repair or replace
(4) Cracks in components...Check and replace
3. CHECK TURBOCHARGING PRESSURE
(a) Warm up the engine.
(b) Using a 3±way connector, connect SST (turbocharger pressure gauge) to the hose leading to the intake air con-
nector.
SST 09992 ± 00242
(c) While depressing the clutch pedal, press the accelerator pedal down to the full. Measure the turbocharging pres-
sure at maximum speed (5,100 to 5,250 rpm).
Standard pressure:
15 to 45 kPa (0.15 to 0.46 kgf/cm
2, 2.2 to 6.5 psi)
If the pressure is less than specification, check both the intake
air and exhaust systems for leakage.
If there is no leakage, check if the actuator hose has discon-
nected. If not, check the turbocharger.
If the pressure is greater than specification, check if the actua-
tor hose has disconnected or cracked. If not, check the turbo-
charger.
4. INSPECT TURBO PRESSURE SENSOR
(a) Inspect power source voltage (1) Disconnect the turbo pressure sensor connector.
(2) Turn the ignition switch ON.
(3) Using a voltmeter, measure the voltage between
connector terminals 3 (VC) and 1 (E2) of the wiring
harness side.
Voltage: 4.5 to 5.5 V
(4) Turn the ignition switch OFF.
(5) Reconnect the turbo pressure sensor connector.

70. INSTALL CYLINDER HEAD SUB±ASSY
HINT:

The cylinder head bolts are tightened in 4 successive
steps (steps (c), (e), (f) and (g)).

If the cylinder head bolt is broken or deformed, replace it
with a new bolt.
(a) Apply a light coat of engine oil on the threads of the cylin-
der head bolts and the plate washers.
(b) Install the plate washer to the cylinder head bolt.
(c) Using several steps, install and tighten the 18 cylinder head bolts uniformly in the sequence shown in the illustra-
tion.
Torque: 45 N

HINT:
See the table below for the bolt length.
Bolt TypeBolt Length
(A)160mm (6.30 in.)
(B)104mm (4.09 in.)
If the cylinder head bolt does not meet the torque specification,
replace the cylinder head bolt with a new bolt.
(d) Mark the front of the cylinder head bolt with paint.
(e) Retighten the cylinder head bolts by 90  in the same se-
quence as step (c).
(f) Retighten the cylinder head bolts by additional 90  in the
same sequence as step (c).
(g) Retighten the cylinder head bolts by one more additional 90 in the same sequence as step (c).
(h) Check that each painted mark is now at the intake man- ifold side.
71. SET NO. 1 CYLINDER TO TDC/COMPRESSION
(a) Using the crankshaft pulley bolt, turn the crankshaft to set the dot mark of the crankshaft timing pulley at the position
of 90  BTDC.
NOTICE:
If the timing belt is disengaged, having the crankshaft tim-
ing pulley at wrong angle can cause the piston head and
valve head to come into contact with each other.

(3)While cranking the engine, measure the compres-
sion pressure.
Compression pressure:
1,300 kPa (13.3 kgf/cm
2, 189 psi)
Minimum pressure:
1000 kPa (10.2 kgf/cm
2, 145 psi)
Difference between each cylinder:
100 kPa (1.0 kgf/cm
2, 14 psi)
NOTICE:

Always use a fully charged battery to obtain engine
speed of 250 rpm or more.

Check other cylinder's compression pressure in the
same way.

This measurement must be done in as short a time as
possible.
(4)If the cylinder compression is low, pour a small amount of engine oil into the cylinder through the
spark plug hole and inspect again.
HINT:

If adding oil increases the compression, the piston rings
and/or cylinder bore may be worn or damaged.

If pressure stays low, a valve may be sticking or seating
improperly, or there may be leakage past the gasket.
10.INSPECT CO/HC
(a)Start the engine.
(b)Run the engine at 2,500 rpm for approximately 180 seconds.
(c)Insert CO/HC meter testing probe at least 40 cm (1.3 ft) into the tail\
pipe during idling.
(d)Check CO/HC concentration at idle. Idle CO concentration: 0 to 0.5 %
Idle HC concentration: Applicable local regulation
(e)If the CO/HC concentration does not conform to specifications, perform troubleshooting in the order given below.
(1)Check heated oxygen sensor operation. (See page 12±6)
(2) See the table below for possible causes, and then inspect and repair the applicable causes ifnecessary.

NOTICE:

Check the drive belt deflection at the specified point.

When installing a new belt, set its tension value as
specified.

When inspecting the belt which is used over 5 min-
utes, apply the specifications of ºUsed Belt.º

When reinstalling the belt which is used over 5 min-
utes, adjust its deflection and tension to the medium
value in each specification of ºUsed Belt.º

V±ribbed belt tension and deflection should be
checked after 2 revolutions of engine cranking.

When using a belt tension gauge, confirm the accura-
cy by using a master gauge first.
(b) Inspect generator V belt. (1) Check that the tension indicator is within range A onthe auto tensioner scale.
If the tension is not within the A range, replace the belt with a
new one.
HINT:
When replacing the drive belt with a new one, the belt tension
should be within the B range.
