Throttle Position Sensor

Throttle Position Sensors (TPS) monitor the angular position of the throttle plate, providing engine control units (ECU) with critical data for fuel injection and ignition timing. Typically located on the throttle body, these sensors utilize a resistive voltage divider or Hall-effect circuit to translate throttle plate angle into an electrical signal. Modern TPS often incorporate non-contact magnetic sensing for improved durability and accuracy. Redundancy via dual-element sensors is increasingly common for enhanced fault tolerance. Signal output is typically analog voltage or digital, communicating directly with the ECU.
