Code P0505 2014 Toyota RAV4 Description

The P0505 diagnostic trouble code (DTC) for a 2014 Toyota RAV4 refers to an issue with the Idle Air Control (IAC) system. The Idle Air Control system plays a crucial role in regulating the engine's idle speed by controlling the amount of air that bypasses the throttle plate. When the engine is idling, the IAC valve adjusts the airflow to maintain a stable idle speed. If the IAC system malfunctions or fails, it can lead to erratic idling, stalling, and poor engine performance.
