Circuit Description
WARNING: This page is about a different car, the 2003 Toyota MR2. However, it is still accessible from the selected car via links, so may be relevant.
Battery voltage is supplied to circuit +BM at ECM harness connector E5 at all times. If DTC P2118 is present, ECM turns off power to throttle motor and magnetic clutch, and throttle valve is fully closed by return spring. When this occurs, opening angle of throttle valve is controlled by accelerator pedal by means of a throttle cable.
