Here are some key facts extracted from the text:
1. The text is a transcript of a video about how to service the throttle body on a Toyota car.
2. The throttle body is a part of the engine that controls the amount of air entering the combustion chamber.
3. Toyota started using a drive-by-wire system for the throttle body around 2002, which means there is no cable connecting the gas pedal to the throttle body, but only sensors and a motor.
4. The throttle body needs to be cleaned regularly (every 25 to 50,000 miles) to remove carbon buildup that can affect the idle speed and smoothness of the engine.
5. To clean the throttle body, one needs to remove the intake hose, open the butterfly valve gently by hand, and use a dedicated throttle plate cleaner and a towel to wipe the contact surface and the edge of the valve.
6. After cleaning the throttle body, the idle speed may be higher at first, but it will adjust over time as the computer learns the new value.
7. One should not use excessive force, screwdrivers, brake cleaner, or other solvents to clean the throttle body, as they can damage the motor, sensors, or catalytic converter.
8. One should also check the 10-amp ECTS fuse if there are problems with the throttle body, as it can blow up when jump-starting the car or when water gets inside the engine.
