NOTE
*1. In a new Vehicle [driven approximately 500 km or less], the air flow sensor output frequency time
is sometimes 10% longer than the standard time.
*2. The injector drive time represents the time when the cranking speed is at 250 r/min or below when
the power supply voltage is 11 V.
*3. In a new vehicle [driven approximately 500 km or less], the injector drive time is sometimes 10%
longer than the standard time.
*4. In a new vehicle [driven approximately 500 km or less], the step of the stepper motor is sometimes
30 steps greater than the standard value.
