(3) Remove the air temperature sensor
(4) Use a hair dryer to increase the temperature and measure the
resistance.
Normal conditions:
air temp. sensor
Temperature (ºC)Resistance (kΩ)
Temperature increasesResistance decreases
(5) If the resistance deviates from the standard values, or if it does
not change, replace the air temperature sensor.
(6) Tighten the air temperature sensor to the specified torque.
Tightening torque: 14 ± N·m
4. Inspection of the oil feeder control valve
Checking the operation of the valve
(1) Disconnect the oil feeder control valve connector.
(2) Apply battery voltage across the terminals of the connector on
the oil feeder control valve side, and check that the sound of the
oil feeder control valve operating can be heard.
Caution
There is a chance that the coil may be damaged, so apply
the voltage in as short a time as possible.
Resistance across the terminals
(1) Remove the oil feeder control valve connector.
(2) Measure the resistance across the terminals of the connector on
the oil feeder control valve side.
Standard value: 6.9~7.9 kΩ (when at 20 ºC)
(3) If the resistance deviates from the standard value, replace the oil
feeder control valve.oil feeder control

Removal guidelines
 
A


Removal of the delivery pipe, the injector and the fuel
pressure regulator ASSY
Remove the deliver pipe, with the injector and the fuel pressure
regulator intact.
Caution
When removing the delivery pipe, be careful not to drop the
injector.
Fitting guidelines



A 

Connecting the O-ring and the fuel high pressure hose
1. Apply a small quantity of fresh engine oil to the O-ring, and
insert it into the delivery pipe without damaging the O-ring.
2. Check that the high pressure hose can be turned smoothly. If it
cannot be turned smoothly there is a possibility that it is biting
into the O-ring, so remove the high pressure hose and check for
any damage to the O-ring. If the O-ring is undamaged, reinsert it
into the delivery pipe and check once more whether the hose
can be turned smoothly.
3. Tighten the mounting bolt to the specified torque.
Tightening torque: 5.0 ± 1.0 N·m

FRONT SUSPENSION – STRUT ASSY33-2
pipe
2. Use the following tools to loosen the self-locking nut.
•Wrench (MB991681)
•Socket (MB991682)
Caution
Do not use an impact wrench when loosening the self-
locking nut, because there is a danger that the lock nut on
the piston rod inside the strut, may work loose.
Assembly guidelines



A 

Fitting the self-locking nut
1. Check that the bearing has completely slotted in.
2. When the coil spring has been compressed using the special
tool, provisionally tighten the self-locking nut.
Caution
Do not use an impact wrench because there is a danger that
the special tool may be damaged.
3. Align the holes in the lower spring plate and the upper spring
plate of the strut ASSY.
Note
This operation can be easily performed by using a pipe to align
the holes.
4. Line up the two ends of the coil spring with the slots in the
spring plate, and loosen the special tool.
5. Use the following special tools to tighten the self-locking nut to
the specified tightening torque.
•Wrench (MB991681)
•Socket (MB991682)
Tightening torque: 60 ± 10 N·m
Caution
Do not use an impact wrench when loosening the self-
locking nut, because there is a danger that the lock nut on
the piston rod inside the strut, may work loose.

2HOW TO USE THIS MANUAL
How to Use this Manual
Range of description
This manual explains the service procedure for the engine after it has been removed from the vehicle. For information on
removing the engine from the vehicle, or "on-vehicle" servicing of the engine, please refer to the separate service manual for
the relevant vehicle model.
Understanding the description
Inspection
The manual only indicates inspection points where special tools or measuring devices are required. It does not mention general
visual checks, part cleaning requirements, and so on, but these must also be carried out as part of the actual service work.
Service sequence
(1) A component diagram is provided at the beginning of each section in order to give the reader a clear
understanding of where the various parts are installed.
(2) The numbers in the component diagram indicate the sequence of the service procedure. Tightening torques
are shown and non-reusable parts are indicated where appropriate
Removal sequence:The part numbers correspond to the numbers in the component diagram and indicate
the removal sequence.
Installation sequence:This is only shown if the parts cannot be installed in the reverse order to the removal
sequence.
Disassembly sequence: The numbers of the part names correspond to the symbols in the component
diagram and indicate the disassembly sequence.
Assembly sequence:This is only shown if the parts cannot be re-assembled in the reverse order to the
disassembly sequence.
Symbols for lubricants and sealants
Application points for lubricants and sealants are
indicated by special symbols (shown right) on the
component parts diagram or on the following page............... Grease
.............. Sealant or liquid gasket (FIPG)
.............. Brake fluid
.............. Engine oil
Types of service points
“Service point” notes are used to give a detailed
description of essential maintenance and service
points, standard values, procedures for using special
tools, and other important information at relevant
points in the service sequence. The different types
of “service point” are shown on the right-hand side.: Indicates that there is a removal or
disassembly service point
: Indicates that there is an installation or
assembly service point
: Indicates that the removal or disassembly
service point is described in the ’01-14G6
DOHC Engine Service Manual.
: Indicates that the installation or assembly
service point is described in the ’01-14G6
DOHC Engine Service Manual.
: Indicates that the removal or disassembly
service point is described in the ’03-14G6
DOHC Engine Service Manual.
: Indicates that the installation or assembly
service point is described in the ’03-14G6
DOHC Engine Service Manual.
