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).

It will return to the "SOFT" state when the brake light is off, and the pedal has been released after 2 seconds or more. (Only 3-stage systems) during hard acceleration; To suppress suspension “squat” the system switches to "HARD" based on accelerator pedal position and throttle position. (Only 3-stage systems) during hard cornering
In cars with electronic throttle control (also known as "drive-by-wire"), an electric actuator controls the throttle linkages and the accelerator pedal connects not to the throttle body, but to a sensor, which outputs a signal proportional to the current pedal position and sends it to the ECU. The ECU then determines the throttle opening based ...
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 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.
The recall affects 3878 Cybertrucks on which a cover on the accelerator pedal can unlatch and get stuck, potentially resulting in unintended acceleration. 2024 Tesla Cybertruck Recalled over ...
Pedal misapplication may be related to pedal design and placement, as in cases where the brake and accelerator are too close to one another, or the accelerator pedal is too large. The NHTSA estimates that 16,000 accidents per year in the United States occur when drivers intend to apply the brake but mistakenly apply the accelerator.
