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 ...

Excessive pressure in the crankcase can force mist of ...
The throttle position sensor(s) are continually read and then the software makes appropriate adjustments to reach the desired amount of engine power. There are two primary types of Throttle Position Sensor (TPS): a potentiometer or a non-contact sensor Hall Effect sensor (magnetic device).

Delco ECU used in General Motors vehicles built in 1996. An engine control unit (ECU), also called an engine control module (ECM), [1] is a device that controls various subsystems of an internal combustion engine.
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.
Throttle body actuator (604) Contains throttle position sensor and throttle motor with associated reduction gear. The throttle body is spherical to improve the throttle area control with low loads. No mechanical limp-home function as with T7. Accelerator position sensor (379) Integrated in accelerator pedal bracket.
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 .
