ENGINE – Timing BeltENGINE – Timing Belt11-17
ETIMING BELT “B” REMOVAL
Make a mark on the back of the timing belt indicating the
direction of rotation so it may be reassembled in the same
direction if it is to be reused.
NOTE
(1) Water or oil on the belt shortens its life drastically, so
the removed timing belt, sprocket, and tensioner must
be free from oil and water. These parts should not be
washed. Replace parts if seriously contaminated.
(2) If there is oil or water on each part check front case
oil seals, camshaft oil seal and water pump for leaks.
FCOUNTERBALANCE SHAFT SPROCKET
REMOVAL
(1) Set the special tool as shown to prevent the
counterbalance shaft sprocket from turning together.
(2) Loosen the bolt and remove the sprocket.
GCRANKSHAFT SPROCKET “B” REMOVAL
If it is difficult to remove the sprocket, use the special tool.
HCAMSHAFT SPROCKET BOLT LOOSENING
Use a wrench to hold the hexagonal part of the camshaft,
and then remove the camshaft sprocket mounting bolt.
INSTALLATION SERVICE POINTS
ACAMSHAFT SPROCKET BOLT TIGHTENING
Using a wrench, hold the camshaft at its hexagon and tighten
the bolt to the specification.

MPI – Troubleshooting13-22
INSPECTION PROCEDURE 5
No initial combustion (starting impossible)
Probable cause
In cases such as the above, the cause is probably that a spark plug is defective,
or that the supply of fuel to the combustion chamber is defective.
In addition, foreign materials (water, kerosene, etc.) may be mixed with the fuel.
Malfunction of the ignition system

Malfunction of the fuel pump system

Malfunction of the injectors

Malfunction of the engine-ECU

Foreign materials in fuel
Check system voltage when cranking.
OK:8 V or higherNGCheck the battery.
OK
MUT-II: Inspection of no initial combustion.
(Refer to P.13-47, INSPECTION PROCEDURE 37.)
OK
Can any sound be heard from the injectors when cranking (check
using a soundscope)?NGCheck the injector system. (Refer to P.13-15, INSPECTION PRO-
CEDURE FOR DIAGNOSIS CODE 41.)
OK
Ignition system: Inspection of no initial combustion.
(Refer to P.13-47, INSPECTION PROCEDURE 38.)
OK
Check the following items.

Check the ignition coil, spark plugs, spark plug cables.

Check if the injectors are clogged.

Check if foreign materials (water, alcohol, etc.) got into fuel.

Check the compression pressure.

MPI – Troubleshooting13-29
INSPECTION PROCEDURE 12
When the engine is hot, it stalls at idling. (Die out)
Probable cause
In such cases as the above, the cause is probably that ignition system, air/fuel mixture,
idle speed control (ISC) or compression pressure is defective.
In addition, if the engine suddenly stalls, the cause may also be a defective connector
contact.
Malfunction of the ignition system

Malfunction of air-fuel ratio control system

Malfunction of the ISC servo system

Drawing air into intake system

Improper connector contact

Backflow of secondary air to the intake system
Were the battery terminals disconnected recently?Ye sAfter warming-up, let the engine run at idling for about 10 minutes.
No
MUT-II Diagnosis code
Are diagnosis codes displayed?Ye sRefer to P.13-8, INSPECTION CHART FOR DIAGNOSIS CODES.
No
Check the ISC servo for operation sound.NGCheck the ISC servo system.
(Refer to P.13-44, INSPECTION PROCEDURE 33.)
OK
Check the injector for operation sound.NGCheck the injector system. (Refer to P.13-15, INSPECTION PRO-
CEDURE FOR DIAGNOSIS CODE 41.)
OK
Does the engine stall right after the accelerator pedal is released?Ye sClean the throttle valve
area.Adjust the fixed SAS.
(Refer to P.13-30.)*
No
Does the engine stall easily again?NoWhile carrying out an intermittent malfunction simulation test (Refer
to GROUP 00 – Points to Note for Intermittent Malfunctions.), check
for sudden changes in the signals shown below.

Crank angle sensor signal

Injector drive signal

Fuel pump drive signal

Air flow sensor signal
Secondary ignition signal

Engine-ECU power supply
voltage
Ye s
MUT-II: Engine stalling inspection when the engine is warm and
idling. (Refer to P.13-50, INSPECTION PROCEDURE 42.)
OK
Check the ignition timing.
(Refer to GROUP 11 – ENGINE ADJUSTMENTS.)*NGCheck that the crank angle sensor and the timing belt cover are
installed properly.
OK
Check the following items.

Check the ignition coil, spark plugs, spark plug cables.

Check the secondary air supply system. (Ensure that there is no backflow of secondary air into the intake system.)

Check if the injectors are clogged.

Check the compression pressure.

Check if foreign materials (water, alcohol, etc.) got into fuel.
