1. When the throttle valve is opened, air flows through the air cleaner, through the air flow meter (on L type systems), past the throttle valve, and through a well tuned intake manifold manifold runner to the intake valve. Air delivered to the engine is a function of driver demand. As the throttle valve is opened further, more air is allowed to enter the engine cylinder.
2. Toyotaengines use two different methods to measure intake air volume. The L type EFI system measures air flow directly by using an air flow meter. The D type EFI system measures air flow indirectly by monitoring the pressure in the intake manifold.
3. The electronic control system consists of various engine sensors, Electronic Control Unit(ECU), and various actuators.
4.There are many sensors such as mass airflow sensor, manifold absolute pressure sensor, throttle position sensor, engine coolant temperature sensor, intake air temperature sensor, crankshaft position sensor, camshaft position sensor
