How does the throttle work on an electric car?

The throttle can open and close according to the instructions from the electric motor. Sensors in the throttle called the throttle position sensors (TPS) will then communicate with the engine management system to let it know it is in the correct position. At the core, the throttle body controls the amount of air that flows into the engine.

How does the electronic throttle work on a truck?

If your truck has a 5.7L Hemi, it becomes even more critical as this engine requires maximum control.
