Electronic Control Unit
In automotive electronics, an electronic control unit (ECU) is an embedded system that controls one or more of the electrical subsystems in a vehicle. Some modern cars have up to 70 ECUs.
In a fuel injection engine, the throttle body is the part of the air intake system that controls the amount of air flowing into the engine, in response to driver input. While the accelerator is often called a "gas pedal", it would be more accurate to describe it as an "air pedal".
The throttle body is usually located between the air filter box and the intake manifold, and usually attached to, or near, the mass airflow sensor.
The largest piece inside the throttle body is the throttle plate, which is a butterfly valve that regulates the airflow.
