Did you knock a wire loose? Have you put everything back the way it was..

If you didn't have the engine light before...common sense tells me you didn't put it back together properly or their is a connection problem.

P0505 (DI-104 ) Idle Control System Malfunction

Common Problems: Idle speed continues to vary greatly from target speed (2 trip detection logic)
 Electric throttle control system
 Air intake (hose loose)





CIRCUIT DESCRIPTION
The idle speed is controlled by the Electric Throttle Control System (ETCS).
ETCS is composed of the throttle motor to operate the throttle valve, the magnetic clutch to connect the
throttle motor with the throttle valve, the throttle position sensor to detect the opening angle of the throttle
valve, the accelerator pedal position sensor to detect the accelerator pedal position, the ECM to control the
ETCS and the one valve type throttle body.
The ECM controls the throttle motor to make the throttle valve opening angle properly for the target idle
speed.


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.

The 1FZ-FE dont have a ETCS ..

( Hose Lose ).. is that mean low air pressure or vacuum in the intake manfolds ..

i'm very sure all the wire are back ..

i want to know which wire or sensore to check ..

the 1FZ-FE like a donkey never bother .. it will keep going ..
