Code P1505 Mercury Description
The P1505 diagnostic trouble code (DTC) for Mercury vehicles indicates a problem with the Idle Air Control (IAC) system reaching the adaptive clip. The IAC system is responsible for controlling the engine's idle speed by managing the amount of air entering the engine. When the system reaches the adaptive clip, it means that the engine control module (ECM) has detected that the IAC system is not functioning within the expected parameters. This can lead to irregular idle speed, stalling, and overall poor engine performance.
