A typical ETC system consists of three major components: (i) an accelerator pedal module (ideally with two or more independent sensors), (ii) a throttle valve that can be opened and closed by an electric motor (sometimes referred to as an electric or electronic throttle body (ETB)), and (iii) a powertrain or engine control module (PCM or ECM).

The predecessor of modern electronic traction control systems can be found in high-torque, high-power rear-wheel-drive cars as a limited slip differential.A limited-slip differential is a purely mechanical system that transfers a relatively small amount of power to the non-slipping wheel, while still allowing some wheel spin to occur.
Output is 225 hp (168 kW; 228 PS) with 240 lb⋅ft (325 N⋅m) of torque in the Camry and 230 hp (172 kW; 233 PS) with 242 lb⋅ft (328 N⋅m) of torque in the Sienna and Highlander. It also features VVT-i, ETCS-i (Electronic Throttle Control System — intelligent/DBW), PA6 plastic intake, and increased throttle body diameter over the 1MZ. The ...
Accelerate-by-wire or throttle-by-wire, [17] more commonly known as electronic throttle control, is a system that actuates vehicle propulsion without any mechanical connections, such as cables, from the accelerator pedal to the throttle valve of the engine or other propulsion systems. In electric vehicles, this system controls the electric ...
The 1KZ-TE also adopts the electronically controlled fuel injection, ETCS-i (Electronic throttle control System - intelligent) technology which is similar in basic construction to a modern gasoline injector, although using considerably higher injection pressures, it is an indirect injection engine which gives it a significant efficiency and ...
The electronic throttle control system (throttle-by-wire) eliminates the mechanical linkage between the accelerator pedal and the throttle plate. Looping the fuel line around the engine improves exhaust gas performance by reducing fuel temperature differences between the delivery pipes, reducing pulsations within the delivery pipes, and ...
Some engine control units (ECUs) also control the throttle position by electronic throttle control (ETC) or "drive by wire" systems, and if that is done, the position sensor is used in a feedback loop to enable that control. [1] Related to the TPS are accelerator pedal sensors, which often include a wide open throttle (WOT) sensor.
Launch control operates by using an electronic accelerator and a computer program in a drive-by-wire application, and through fuel or spark cut in a mechanical throttle application. The software can control acceleration based on engine specifications to make the car accelerate smoothly and as fast as possible, avoiding spinning of the drive ...
