  2. TorqueFlite - Wikipedia

    en.wikipedia.org/wiki/TorqueFlite

    The 48RE was introduced in 2004 to 3rd gen ram pickups with the 5.9 cummins, or the v10, some 03 and early 04 trucks still were equipped with 47RE units, and then came a 48re which still used a TV cable, and then from 04.5-07 the 48re was fitted with a TTVA motor (transmission throttle valve actuator) which eliminated the need for a mechanical ...

  3. Electronic throttle control - Wikipedia

    en.wikipedia.org/wiki/Electronic_throttle_control

    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).

  4. Sudden unintended acceleration - Wikipedia

    en.wikipedia.org/wiki/Sudden_unintended_acceleration

    Other problems may be implicated in the case of older vehicles equipped with carburetors. Weak, disconnected, or mis-connected throttle return springs, worn shot-pump barrels, chafed bowden cable housings, and cables which jump their tracks in the throttle-body crank can all cause similar acceleration problems.

  5. Desmodromic valve - Wikipedia

    en.wikipedia.org/wiki/Desmodromic_valve

    The common valve spring system is satisfactory for traditional mass-produced engines that do not rev highly and are of a design that requires low maintenance. [1] At the period of initial desmodromic development, valve springs were a major limitation on engine performance because they would break from metal fatigue.

  6. Drive by wire - Wikipedia

    en.wikipedia.org/wiki/Drive_by_wire

    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 ...

  7. Throttle position sensor - Wikipedia

    en.wikipedia.org/wiki/Throttle_position_sensor

    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.

  8. Traction control system - Wikipedia

    en.wikipedia.org/wiki/Traction_control_system

    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.

  9. Throttle - Wikipedia

    en.wikipedia.org/wiki/Throttle

    In fuel injected engines, the throttle body is the part of the air intake system that controls the amount of air flowing into the engine, in response to driver accelerator pedal input in the main. The throttle body is usually located between the air filter box and the intake manifold, and it is usually attached to, or near, the mass airflow sensor.
