NOTE
*1: In a new vehicle [driven approximately 500 km or less], the air intake plenum pressure is sometimes
10 % higher than the standard pressure.
*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.
