Is the 2004 Toyota Echo a drive by wire throttle?

Here's why:

* Drive-by-wire systems use electronic signals to control the throttle, eliminating the physical cable connection between the accelerator pedal and the throttle body.

* Cable-operated systems rely on a physical cable to link the accelerator pedal to the throttle body.

Drive-by-wire systems were not common in vehicles like the 2004 Echo, which was a smaller, more affordable car.
