Circuit Description
WARNING: This page is about a different car, the 2002 Toyota Land Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
Magnetic clutch is located between throttle control motor and throttle body. Throttle motor opens and closes throttle valve by using the magnetic clutch. DTC is set if magnetic clutch current is not within specified range. If DTC P1126 exists, ECM will turn off the power to throttle control motor and throttle valve is closed by the return spring. When this occurs, throttle valve is controlled by throttle cable connected to accelerator pedal. Possible causes are:
- Magnetic clutch circuit is open or shorted.
- Defective magnetic clutch.
- Defective ECM.
