Throttle Position Sensor (TPS)
The TPS, mounted on throttle body, delivers an input signal indicating throttle position to the Engine Control Module (ECM). The ECM uses input signal for controlling fuel injection system, ignition timing (spark advance), idle speed control system, fuel pressure control system (if equipped), A/C-cut control system (if equipped), EGR system (if equipped), intake air control valve system or variable induction system (if equipped) and automatic transmissions/transaxles (some models).
