6. Remove the outer plate (7) with the screw driver and
remove the link (5).
7. Connect the new timing chain (2) to the used timing
chain (3) with the link (5), center plate (6, thickness
1.6mm), and the outer plate (7).
8. Rotate the crankshaft in the direction if engine revo-

10. Connect both separators of the new timing chain
with the link (5) and the center plate (6).
11. Install the jaw (a) and the thrust piece (b) to the as-
sembly tool as shown in the figures.

OIL NON-- RETURN VALVE
Preceding Work: Removal of timing gear case cover
1 Oil Non-- return Valve
Functions
The non -- return valve prevents the oil in the chain ten-
sioner from drying up. In other words, it stops oil-- return-
ing in order to prevent the oil in the chain tensioner from
getting dry. As a result, the chain tensioner can be acti-
vated with oil in itself.
Replacement Procedure
1. Remove the non--return valve using a pliers.
2. Insert new non-- return valve with hand.

IGNITION SYSTEM
This ignition system does not use a conventional distributor andcoil. It uses a crankshaft position sensor input to the
Engine Control Module (ECM). The ECM then determines Electronic Spark Timing (EST) and triggers the electronic
ignition system ignition coil.
This type of distributorless ignition system uses a‘‘waste spark” method of spark distribution. Each cylinder is paired
with the cylinder that is opposite it (2 -- 3 or 1 -- 4). The spark occurs simultaneously in the cylinder coming up on the
compression stroke and in the cylinder coming up on the exhaust stroke. The cylinder on the exhaust stroke requires
very little of the available energy to fire the spark plug. The remaining energy is available to the spark plug in the cylin-
der on the compression stroke.
These systems use the EST signal from the ECM to control the EST. The ECM uses the following information:
DEngine load (mass air flow sensor).
DEngine temperature.
DIntake air temperature.
DCrankshaft position.
DEngine speed (rpm).

Circuit Description
The Electronic Ignition (EI) system uses a waste spark method of spark distribution. The Crankshaft Position (CKP)
sensor sends reference pulses to the ECM. The ECM then triggers the EI system ignition coils. Once the ECM triggers
the EI system ignition coils both of the connected spark plugs fire at the same time. One cylinder is on its compression
stroke at the same time that the other is on the exhaust stroke, resulting in lower energy needed to fire the spark plug in
the cylinder on its exhaust stroke.
This leaves the remainder of the high voltage to be used to fire the spark plug in the cylinder on its compression stroke.
Since the CKP sensor is in a fixed position, timing adjustments are not possible or needed.

KNOCK SENSOR (KS)
YAA1F320
The Knock Sensor (KS) detects abnormal knocking in the engine. The two KS are mounted in the engine block near
the cylinders. The sensors produce an output voltage which increases with the severity of the knock. This signal is sent
to the Engine Control Module (ECM) via a shielded cable. The ECM then adjusts the ignition timing to reduce the spark
knock.
