HOW TO USE THIS MANUAL
GENERAL INFORMATION
1. GENERAL DESCRIPTION
(a) This manual is made in accordance with SAE J2008.
(b) Generally, repair operations can be separated in the following 3 main processes:
1. Diagnosis
2. Removing/Installing, Replacing, Disassembling/Reassembling, Checking and Adjusting
3. Final Inspection
(c) This manual explains the 1st process of ºDiagnosisº (found in the ºDiagnosticsº section), the 2nd
pro-
cess of ºRemoving and Installing, Replacing, Disassembling, Installing and Checking, and Adjustingº,
but the 3rd process of ºFinal Inspectionº is omitted.
(d) The following essential operations are not written in this manual. However, these operations must be
performed in actual situations.
(1) Operations with a jack or lift
(2) Cleaning of a removed part when necessary
(3) Visual check
2. INDEX
(a) An alphabetical INDEX section is provided at the end of the book as a reference to help you find the
item to be repaired.
3. PREPARATION
(a) Use of special service tools (SST) and special service materials (SSM) may be required, depending
on the repair situation. Be sure to use SST and SSM when they are required and follow the working
procedure properly. A list of SST and SSM is in the Preparation section of this manual.

AVENSIS REPAIR MANUAL (RM1018E)
3. INJECTION CONTROL SYSTEM
The ECM controls the fuel injection system using the injector and the supply pump. The ECM determines
the fuel injection volume and injection timing by controlling duration and timing of the energizing to the sole-
noid valve of the injector, and determines injection pressure by controlling the Suction Control Valve located
on the supply pump.
The feed pump is used to pump fuel from the fuel tank into the supply pump.

(3) While cranking the engine, measure the compres-
sion pressure.
Compression pressure


1,300 kPa (13.3 kgf
cm
2, 189 psi)
Minimum pressure: 1,000 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 in one or more cylinders
is low, pour a small amount of engine oil into the cyl-
inder through the spark plug hole and repeat steps
(1) through (3) for the cylinders that have low com-
pression.
HINT:

If adding oil helps increase 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 tailpipe during idling.
(d) Check CO/HC concentration at idle.
Idle CO concentration: 0 to 0.5 %
Idle HC concentration: Applicable local regulation
If the CO/HC concentration does not conform to specifications, perform troubleshooting in the order given
below.

Check heated oxygen sensor operation.

See the table below for possible causes, and then inspect and repair the applicable causes if
necessary.

27. REMOVE CHAIN SUB±ASSY
(a) Remove the timing chain with the crankshaft timing gear
by plying it using screwdrivers as shown in the illustration.
NOTICE:

Put shop rag to protect the engine.

In case of revolving the camshafts with the chain off
the sprockets, turn the crankshaft 1/4 revolution
counterclockwise for valves not to touch the pistons.
28. INSTALL CHAIN SUB±ASSY
(a) Set No. 1 cylinder to TDC/compression.
(1) Turn the camshafts with a wrench and align the
point marks of the camshaft timing sprockets.
(2) Using a crankshaft pulley bolt, turn the crankshaft
and set the set key on the crankshaft upward.
(b) Install the timing chain to the crankshaft timing sprocket
with the yellow color link aligned with the timing mark on
the crankshaft timing sprocket.
HINT:
Three yellow color links are on the chain.
(c) Using SST, install the crankshaft timing sprocket.

46. REMOVE CHAIN SUB±ASSY
(a) Remove the timing chain by prying the crankshaft timing
gear using screwdrivers as shown in the illustration.
NOTICE:

Put shop rag to protect the engine.

In case of revolving the camshafts with the chain off
the sprockets, turn the crankshaft 1/4 revolution
counterclockwise to prevent the valves from touch-
ing the pistons.
47. REMOVE CAMSHAFT
(a) Using several steps, loosen and remove the 19 bearing
cap bolts uniformly in the sequence shown in the illustra-
tion. Remove the 9 bearing caps, and both the intake and
exhaust camshafts.
48. REMOVE CYLINDER HEAD SUB±ASSY
(a) Using several steps, loosen and remove the 10 cylinder
head bolts with a 10 mm hexagon wrench uniformly in the
sequence shown in the illustration. Remove the 10 cylin-
der head bolts and 10 plate washers.
(b) Remove the cylinder head.
49. REMOVE CYLINDER HEAD GASKET
50. INSTALL CYLINDER HEAD GASKET
(a) Place a new cylinder head gasket on the cylinder block
with the Lot No. stamp facing upward.
NOTICE:

Pay attention to the mounting orientation.

Place the cylinder head on the gasket gently in order
not to damage the gasket with the bottom part of the
head.
51. INSPECT CYLINDER HEAD SET BOLT
(a) Using a vernier calipers, measure the length of cylinder
head bolt from the seat to the end.
Standard length: 146.8 to 148.2 mm (5.780 to 5.835 in.)
Maximum length: 148.5 mm (5.846 in.)
If the length exceeds the maximum, replace the bolt.
