Throttle Position (TP) Sensor

The TP sensor, mounted on throttle body, delivers an input signal indicating throttle position to the Engine Control Module (ECM). The ECM may use input signal for controlling fuel injection system, ignition timing (spark advance), idle speed control system, A/C-cut control system (if equipped), intake air control valve system (if equipped), EGR system (if equipped) and electronically controlled automatic transmissions/transaxles.

NOTE: Vapor pressure sensor may be referred to as EVAP vapor pressure sensor. Vapor pressure sensor VSV may be referred to as EVAP Vapor Pressure Sensor Vacuum Switching Valve (EVAP-VPSVSV).
