|What is P0507 1997 FORD F150 code meaning?

The Idle Air Control (IAC) valve assembly is used to control idle speed and provide a dashpot function. IAC valve assembly meters inlet air around the throttle plate through a by-pass within the IAC valve assembly and throttle body.
The Powertrain Control Module (PCM) determines desired idle speed or air by-pass and signals the IAC valve assembly through a specified duty cycle. The IAC solenoid is built into the IAC valve assembly. IAC solenoid responds by positioning the IAC valve to control the amount of air by-passed. PCM monitors engine speed and adjust the IAC duty cycle to achieve the desired RPM. IAC valve assembly is not adjustable and cannot be cleaned. The Diagnostic Trouble Code (DTC) will set when the idle speed is more than the target idle speed by 200 rpm or more.
