Engine-ECU Monitor Item
•Items useful for grasping the engine control condition by the engine-ECU are provided in this monitor item
section.
•Values of these monitor items vary greatly depending on marginal difference of measurement conditions,
difference of the environment, aged deterioration of vehicl es and so on, and it is difficult to show the pre
-
cise specification values. Therefore, check conditions, display range and movement of values are
described.

The electronic device is basically the same as that in
the conventional 4G1 engine.
The employed alternator is a lightweight type in
which the electronic voltage regulator for detecting
the battery voltage is built.
The employed starter motor is a small planetary gear
reduction drive type.
The employed spark plug is a long reach type with
iridium.
The employed ignition coil is a plug top type in which
the powertrain per cylinder is built.
