A throttle position sensor (TPS) is a sensor used to monitor the throttle body valve position for the ECU of an engine. The sensor is usually located on the butterfly spindle/shaft, so that it can directly monitor the position of the throttle. More advanced forms of the sensor are also used. For example, an extra "closed throttle position ...
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).

A federal vehicle safety regulator says it has contacted Tesla after a Cybertruck owner went viral over the weekend with claims that his accelerator pedal got stuck while he was driving the vehicle.
The throttle, which controls fuel and air supply to the engine and is also known as the "accelerator" or "gas pedal", is normally the right-most floor pedal. It has a fail-safe design – a spring, which returns it to the idle position when not depressed by the driver.
The functional objective for the crankshaft position sensor is to determine the position and/or rotational speed of the crank. Engine Control Units use the information transmitted by the sensor to control parameters such as ignition timing and fuel injection timing. In a diesel, the sensor will control the fuel injection.
The accelerator pedal becomes harder to depress or slower to return to the closed position. The accelerator pedal may become stuck in a partially depressed position. Should the pedal become stuck while driving, drivers should switch to neutral and stop. A repair fix would be applied by the manufacturer to prevent the sticky pedal condition.
Wide open throttle or wide-open throttle (WOT), also called full throttle, is the fully opened state of a throttle on an engine (internal combustion engine or steam engine). The term also, by extension, usually refers to the maximum-speed state of running the engine, as the normal result of a fully opened throttle plate/ butterfly valve .
