Code P0505 2006 Toyota Camry Description

The idle speed is controlled by the Electronic Throttle Control System (ETCS). The ETCS is composed of the throttle motor, which operates the throttle valve, and the throttle position sensor, which detects the opening angle of the throttle valve. The Engine Control Module (ECM) controls the throttle motor to provide the proper throttle valve opening angle to obtain the target idle speed.
