Abstract

The Ford P1506 error code indicates that your idle air control (IAC) system is experiencing an over-speed condition. This means the engine is idling at a higher RPM than normal, typically above 1200 RPM when it should be around 600-800 RPM. This issue can cause poor fuel economy, rough idling, and potential engine damage if left unaddressed.
