Throttle Position Sensor

Throttle Position Sensors (TPS) are vital components within a vehicle's engine management system, monitoring the position of the throttle plate. Located on the throttle body, these sensors accurately report engine load and driver demand to the Engine Control Unit (ECU). This information is crucial for precisely controlling fuel delivery, ignition timing, and idle speed - optimizing engine performance and fuel efficiency. TPS units utilize a potentiometer or other resistive element to translate throttle plate angle into an electrical signal. Examples within our Engine Parts > Engine Electronics > Throttle Position Sensor category include sensors for MAN vehicles, such as part number 81473016067 and 51055040122. Proper TPS function ensures smooth acceleration, correct idle, and avoids engine hesitation or stalling.
