• All dimensions indicated in the figures are actual.
• When using a tracking gauge, adjust both pointers to equal length. Then check the pointers and gauge itself
to make sure there is no free play.
• When a measuring tape is used, check to be sure there is no elongation, twisting or bending.
• Measurements should be taken at the center of the mounting holes.
• An asterisk (*) following the value at the measuring point indicates that the measuring point on the other side
is symmetrically the same value.
• The coordinates of the measurement points are the distances measured from the standard line of ″X ″, ″Y ″

20. Remove water pump:
a. Screw M8 bolts approximately 50 mm (1.97 in) into water pump upper and lower bolt holes until they reach the timing chain case
[M8 bolt pitch 1.25 mm (0.49 in) length].
CAUTION:
• Place a suitable shop cloth below the water pump hous-
ing to prevent any co olant from dripping into the timing
chain case.
• Pull water pump straight out while preventing vane from
contacting socket in installation area.
• Remove water pump without causing sprocket to contact
timing chain.
b. Remove M8 bolts and O-rings from water pump. CAUTION:
Do not reuse O-rings.
INSPECTION AFTER REMOVAL
• Visually check for significant dirt or rust on the water pump body and vane.
• Check that the vane shaft turns smoothly by hand and is not
excessively loose.
• Replace the water pump assembly if the water pump does not per- form properly.
INSTALLATION
1. Install new O-rings on water pump (1).
CAUTION:
Do not reuse O-rings.
a. Apply engine oil to the O-rings (2,3) as shown.
b. Locate the O-ring (2) with white paint mark (A) to engine front side.
2. Hold timing chain to the side ( ) and install the water pump ().
CAUTION:
Do not allow the O-rings to be damaged by the cylinder
block when installing the water pump.
• Check that timing chain and water pump sprocket are
engaged.
• Tighten water pump bolts alternately and evenly to specifica- tion.
3. Remove dust and foreign material completely from installation area of timing chain tensioner and rear tim- ing chain case.

COMPONENT PARTS
THROTTLE CONTROL MOTOR RELAY
Power supply for the throttle control motor is provided to
the ECM via throttle control motor relay. The throttle
control motor relay is ON/OFF controlled by the ECM. When the ignition switch is turned ON, the ECM sends
an ON signal to throttle control motor relay and battery voltage is provided to the ECM. When the ignition
switch is turned OFF, the ECM sends an OFF signal to throttle control motor relay and battery voltage is not
provided to the ECM.
THROTTLE CONTROL MOTOR
The throttle control motor is operated by the ECM and it opens and closes the throttle valve.
The current opening angle of the throttle valve is detected by the throttle position sensor and it provides feed-
back to the ECM to control the throttle control mo tor to make the throttle valve opening angle properly in
response to driving condition.
THROTTLE POSITION SENSOR
The throttle position sensor responds to the throttle valve movement.
The throttle position sensor has two sensors. These sensors are a
kind of potentiometers which transform the throttle valve position into
output voltage, and emit the voltage signal to the ECM. In addition,
these sensors detect the opening and closing speed of the throttle
valve and feed the voltage signals to the ECM. The ECM judges the
current opening angle of the throttle valve from these signals and the
ECM controls the throttle control motor to make the throttle valve
opening angle properly in response to driving condition.
Ignition Coil With Power TransistorINFOID:0000000009462057
The ignition signal from the ECM is sent to and amplified by the
power transistor. The power transistor turns ON and OFF the ignition
coil primary circuit. This ON/OFF operation induces the proper high
voltage in the coil secondary circuit.
Fuel InjectorINFOID:0000000009462058
The fuel injector is a small, precise solenoid valve. When the ECM
supplies a ground to the fuel injector circuit, the coil in the fuel injec-
tor is energized. The energized coil pulls the ball valve back and
allows fuel to flow through the fuel injector into the intake manifold.
The amount of fuel injected depends upon the injection pulse dura-
tion. Pulse duration is the length of time the fuel injector remains
open. The ECM controls the injection pulse duration based on
engine fuel needs.

SYSTEM DESCRIPTION
The amount of fuel injected from the fuel injector is determined by the ECM. The ECM controls the length of
time the valve remains open (injection pulse duration). T he amount of fuel injected is a program value in the
ECM memory. The program value is preset by engi ne operating conditions. These conditions are determined
by input signals (for engine speed and intake air) from t he crankshaft position sensor (POS), camshaft position
sensor (PHASE) and the ma ss air flow sensor.
VARIOUS FUEL INJECTION I NCREASE/DECREASE COMPENSATION
In addition, the amount of fuel injected is compens ated to improve engine performance under various operat-
ing conditions as listed below.
• During warm-up
• When starting the engine
• During acceleration
• Hot-engine operation
• When selector lever is changed from N to D
• High-load, high-speed operation
• During high engine speed operation
