THROTTLE VALVE OPENING ANGLE CONTROL AND IDLE SPEED CONTROL

Compensations
Battery voltage compensation
[Control for checking ignition timing]
During basic ignition timing set mode for M.U.T.-III
actuator test function, sparking is done with fixed
ignition timing (5° BTDC) synchronized with crank-
shaft position sensor signal.
THROTTLE VALVE OPENING ANGLE CONTROL AND IDLE
Engine-ECU detects the amount of accelerator pedal
depression (as per operator's intention) through the
accelerator pedal position sensor. Based on pre-set
basic target opening angles it adds various compen-
sations and controls the throttle valve opening angle
according to the target opening angle.
While starting
Engine-ECU adds various compensations to the tar-
get opening angle that are set based on the engine
coolant temperature, so that the air volume is opti-

Content
Compensation is made depending on battery
voltage. The lower the battery voltage the greater
the current carrying time and when battery voltage
is high current carrying time is shortened.
