P1126 TOYOTA Meaning

The magnetic clutch is mounted between the throttle motor and the valve, and it connects the throttle motor to the throttle valve.
Therefore, the throttle motor opens and closes the throttle valve via the magnetic clutch.
In case of malfunction in the electronic throttle control system, the magnetic clutch separates the throttle motor from the throttle valve so as not to operate the throttle valve by the throttle motor.
If code P1126 is stored, the engine control module (ECM) cuts off power to the throttle motor and the magnetic clutch, and the throttle valve is completely closed by the return spring.
However, the throttle valve opening angle can be controlled by the accelerator pedal via the accelerator cable.
