Caution
1. Always apply the brakes when shifting the select or lever to ran&, or vehicle will
forward.
2. Driving tests always need another personnel.
NOTE
In a new vehicle [driven approximately 500 km (300 mile) or less], the volume air sensor output
is sometimes 10 higher than the standard frequency.
The injector drive time represents the time when the cranking speed is at 250 or below when the
supply voltage is 11 V.
In a new vehicle [driven approximately 500 km (300 mile) or less], the injector drive time is sometimes
longer than the standard time.
Fuel is injected into all cylinders simultaneously.
In a new vehicle [driven approximately km (300 mile) or less], the step of the stepper mo tor is sometimes
30 steps greater than the standard value.
If the throttle position sensor voltage rises 100 from the voltage when the engine is at idle and th e
closed throttle position switch turns from on to of f at this time, the sensors are normal. If the throttle position
sensor voltage rises 100
from the voltage when the engine is at idle, the t hrottle valve opens, and the
closed throttle position switch turns from on to of f at this, time, the sensors should be adjusted.
