Electronic Control Throttle System

2007 Subaru Outback Limited, 4D Sedan, StandardSECTION Electronic Control Throttle System
  • The electronic control throttle system consists of an accelerator pedal position sensor mounted on the accelerator pedal, a throttle position sensor and a throttle motor mounted on the throttle body, and the ECM, which controls these devices.
  • The movement of the accelerator pedal is converted into electrical signals by the accelerator pedal position sensor and sent to the ECM. Based on these signals the ECM controls the throttle motor to open and close the throttle valve.
  • Idling control is now performed by the electronic control throttle system in place of the idle air control solenoid valve.
