Code P0505 2015 Toyota RAV4 Description

The idle speed is controlled by the Electronic Throttle Control System (ETCS). The ETCS is comprised of 1) the one valve type throttle body; 2) the throttle actuator, which operates the throttle valve; 3) the throttle position sensor, which detects the opening angle of the throttle valve; 4) the accelerator pedal position sensor, which detects the accelerator pedal position; and 5) the Engine Control Module (ECM), which controls the ETCS. Based on the target idle speed, the ECM controls the throttle actuator to provide the proper throttle valve opening angle.
The ECM monitors the idle speed and idling airflow volume to conduct Idle Speed Control (ISC). The ECM determines that the ISC system is malfunctioning if the Idle speed continues to vary greatly from the target idle speed.
