Circuit Description

Magnetic clutch is mounted between throttle control motor and throttle body. Throttle motor opens and closes throttle valve through magnetic clutch. If magnetic clutch is defective, throttle control motor must be replaced. If DTC P1126 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. DTC is set when ECM detects out of range throttle control motor current. Possible causes are:

• Magnetic clutch circuit is open or shorted.
• Defective magnetic clutch.
• Defective ECM.
