Periodic Maintenance and Adjustment 8-7
The output power and torque are adjusted
by changing the injection quantity.
Water Temperature Sensor
This sensor is used to monitor the water
temperature. Based on the water
temperature, the ECU can automatically
adjust the injection quantity to assure the
stability of the engine.
Ignition signal
The generator provides the ECU with the
proper ignition timing signal.
At the center of the EFI system, this model
adopts a specially designed microcomputer
chip controller, which controls the injection
quantity by calculating the information
gathered by the sensors. This enables the
engine to operate with better fuel
consumption and less emissions.
EFI system examination
If the EFI system fails, the associated fault
code is shown on the display panel. You
can diagnose the system using an EFI
scanner (purchased from your dealer). This
scanner provides detailed fault code
information. An owner’s manual for the fault
code is available.
