Code P0506 2000 Ford F150 Description
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 less than the target idle speed by 100 rpm or more.

- Check for Vacuum Leaks
- Faulty Idle Air Control (IAC) Valve
- Idle Air Control Valve harness is open or shorted
- Idle Air Control Valve circuit poor electrical connection
- Faulty Powertrain Control Module (PCM)
