About TOYOTA VITZ Computers & Sensors Spare Parts
To keep the Toyota Vitz's engine running at maximum efficiency, it makes use of its engine computer unit, or the ECU for short. The computer monitors the status and performance levels of various components and detects changes with the help of different sensors. It then responds appropriately by increasing mileage efficiency and lowering fuel consumption, such as by controlling the length of time fuel injectors are open and manipulating the spark plugs to produce the best spark timing. Such sensors include the engine temperature sensor, air pressure sensor, air temperature sensor, oxygen sensor, and knock sensor. The computer also alerts the driver to avoid further damage when there are anomalies in the engine. When the "check engine" light turns on, that is the engine's computer playing its role.
Newer model years of the Vitz come with more sophisticated safety systems controlled by the ECU, allowing the driver to enjoy such automated features as the automatic braking system, traction and stability control, and airbags. If the engine is modified, the ECU may need to be reprogramed or upgraded to be able to accommodate these changes.
