2. Generator Pulley
A helical coil type one-way clutch is used on the generator pulley in order to reduce the load that acts on
the auxiliary equipment belt.
The pulley mounting nut and the generator pulley have been integrated to achieve a compact construction.

8. Cooling Fan Control
On the models with air conditioning, the ECM controls the operation of the cooling fan in two speeds (Low
and High) based on the engine coolant temperature sensor signal and the air conditioning ECU signal. This
control is accomplished by operating the 2 fan motors in 2 stages through low speed (series connection) and
high speed (parallel connection).

2) MRE Type VVT Sensor
The MRE type VVT sensor consists of an MRE, a magnet and a sensor. The direction of the magnetic
field changes due to the different shapes (protruded and non-protruded portions) of the timing rotor,
which passes by the sensor. As a result, the resistance of the MRE changes, and the output voltage to
the ECM changes to Hi or Lo. The ECM detects the camshaft position based on this output voltage.
The differences between the MRE type VVT sensor and the pick-up coil type VVT sensor used on
the conventional models are as follows.
ItemSensor TypeItemMREPick-up Coil
Signal OutputConstant digital output starts from
low engine speeds.Analog output changes with the
engine speed.
Camshaft Position
Detection
Detection is made by comparing
the NE signals with the Hi / Lo
output switch timing due to the
protruded / non-protruded portions
of the timing rotor, or made based
on the number of the input NE
signals during Hi / Lo outputs.
Detection is made by comparing
the NE signals with the change of
waveform that is output when the
protruded portion of the timing
rotor passes.

12. Cooling Fan Control System
General
A cooling fan control system is used. To achieve an optimal fan speed in accordance with the engine coolant
temperature, vehicle speed, engine speed, and air conditioning operating conditions, the ECM calculates
the proper fan speed and sends the signals to the front controller. By receiving the signals from the ECM,
the front controller sends proper fan speed control signals to the cooling fan ECU.
Upon receiving the signals from the front controller, the cooling fan ECU actuates the fan motors.
