Functions
1. Firing order : 1 -- 5 -- 3 -- 6 -- 2 -- 4
2. The ignition cables are located on the cylinder head
cover. Each ignition coil provides the high voltage to
two spark plugs simultaneously.
-- T1/1 : cylinder 2 and 5
-- T1/2 : cylinder 3 and 4
-- T1/3 : cylinder 1 and 6
3. The secondary output voltage (5a) is supplied to the
No.2 cylinder spark plug through the spark plug con-
nector. The secondary output voltage (5b) is supplied
to the No.5 cylinder spark plug through the ignition
cable. The guide pin (W) acts as a ground while the
ignition cable is operated.
Removal & Installation Procedure
1. Disconnect the negative battery cable (1).
2. Remove the ignition cable connector from the ignition
cable.
3. Disconnect the secondary spark plug connectors
from the each spark plugs and remove the ignition
cable bolt and ignition cable.

CAMSHAFT ACTUATOR
YAA1F300
When the engine is running, the camshaft actuator rotates the intake camshaft hydraulically and mechanically relative
to the camshaft sprocket by 32°crank angle to the “advanced” position and back to the “retard” position.
The camshaft actuator is actuated electro-mechanically by the Engine Control Module (ECM). The positioning time of
apporx. 1 second is dependent on the engine oil pressure at the camshaft actuator and on the oil viscosity and oil
temperature, respectively.
The camshaft indicator on the camshaft sprocket provides the camshaft rotational speed to the position sensor as an
input parameter for the engine ignition control unit.

INDUCTION SYSTEM
THROTTLE VALVE ACTUATOR
YAA1F540
The throttle actuator is actuated by the Engine Control Module (ECM) according to the position of the accelerator pedal
position.
It has two potentiometers which signal the position of the throttle valve to the ECM to enable it to recognize the various
engine load states.
Ignition “Off”
In the de-- energized states the throttle valve position is determined to be spring capsule.
Ignition “On”
When the ignition S/W on the servo motor in the throttle actuator is operated by the ECM. The throttle valve adopts a
position in line with the coolant temperature.
Closed position
In the closed throttle position, the servo motor controls engine speed by operating the throttle valve further (greater
mixture) or closing it further (reduced mixture), depending on coolant temperature and engine load. When this is done,
the throttle valve can be closed further by the servo motor overcoming the force of the spring capsule (mechanical end
stop). If the actuator is de-- energized, the throttle valve is resting against the spring capsule.
Consequently, the throttle valve opening is a constant 10-- 12°approximately.
At no load, this produces an engine speed of about 1,800 rpm
Driving
When driving (part/full throttle), the servo motor controls the throttle valve in line with the various load states and ac-
cording to the input signals from the pedal value sensor according to the input signals from the pedal value sensor
according to the position of the accelerator pedal.
The function of the EA (electronic accelerator) in the ECM determines the opening angle of the throttle valve through
the throttle actuator. Further functions are;
DIdle speed control
DCruise control
DReducing engine torque for ASR/ABS operation
DElectronic accelerator emergency running
DStoring faults
DData transfer through CAN

ENGINE COOLANT TEMPERATURE (ECT) SENSOR
YAA1F590
Engine Coolant Temperature (ECT) sensor detects coolant temperature and supplies information to the ECM. It is
composed of metal housing with two NTC resistor, 4 pin connector. The ECM provides a 5 volt signal to the ECT
sensor through a dropping resistor. When the engine is cold, the ECT sensor provides high resistance, which the ECM
detects as a high signal voltage. As the engine warms up, the sensor resistance becomes lower, and the signal voltage
drops. At normal engine operating temperature, the ECT signalwill measure about 1.5 to 2.0 volts.
The ECM uses information about coolant temperature to make the necessary calculations for:
DFuel delivery
DIgnition control
DKnock sensor system
DIdle speed
DTorque converter clutch application
DCanister purge
DCooling fan operation
