Step 3
INSPECTION PROCEDURE
HINT: Read freeze frame data using TOYOTA hand-held tester or OBD II scan tool. Because freeze frame records the engine conditions when
the malfunction is detected, when troubleshooting it is useful for determining whether the vehicle was running or stopped, the engine warmed up or
not, the air-fuel ratio lean or rich, etc. at the time of the malfunction.
DTC P1126 Magnetic Clutch Circuit Malfunction
DTC P1126 Magnetic Clutch Circuit Malfunction
CIRCUIT DESCRIPTION
Magnetic clutch is mounted between the throttle motor and the valve, and it connects the throttle motor with the throttle valve.
Therefore, the throttle motor opens and closes the throttle valve through the magnetic clutch.
If the electric throttle control system has a malfunction, the magnetic clutch separates the throttle motor from the throttle valve in order not to
operate the throttle valve by the throttle motor.
If this DTC is stored, the ECM shuts down the power for the throttle motor and the magnetic clutch, and the throttle valve is fully closed by the
return spring.
However, the opening angle of the throttle valve can be controlled by the accelerator pedal through the throttle cable.
