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.
Often a throttle position sensor (TPS) is connected to the shaft of the throttle plate to provide the ECU with information on whether the throttle is in the idle position, wide-open throttle (WOT) position, or somewhere in between these extremes. Throttle bodies may also contain valves and adjustments to control the minimum airflow during idle.
In addition to defining the reference frames, the relative orientation of the reference frames can be determined. The relative orientation can be expressed in a variety of forms, including: Rotation matrices; Direction cosines; Euler angles; Quaternions; The various Euler angles relating the three reference frames are important to flight dynamics.
Instead, the position of the throttle valve (i.e., the amount of air in the engine) is fully controlled by the ETC software via the electric motor. But just opening or closing the throttle valve by sending a new signal to the electric motor is an open loop condition and leads to inaccurate control.

The way they do this is during a deceleration of the vehicle when there is low absolute pressure in the intake manifold (i.e., a high vacuum present in the intake manifold relative to the outside air) the powertrain control module (PCM) will open the EGR valve and then monitor the MAP sensor's values. If the EGR is functioning properly, the ...

Thrust levers in a Boeing 747 Classic. The center and rear levers are used during flight, while the forward levers control reverse thrust.. Thrust levers or throttle levers are found in the cockpit of aircraft, and are used by the pilot, copilot, flight engineer, or autopilot to control the thrust output of the aircraft's engines, by controlling the fuel flow to those engines.
