Circuit Description
WARNING: This page is about a different car, the 2003 Toyota 4Runner. However, it is still accessible from the selected car via links, so may be relevant.
The idle speed is controlled by the Electric Throttle Control System (ETCS). ETCS is composed of:
- Throttle motor to operate the throttle valve.
- Throttle position sensor to detect the opening angle of the throttle valve.
- Accelerator pedal position sensor to detect the accelerator pedal position.
- ECM to control the ETCS, and the one valve type throttle body.
