P0506 2007 Ford Fusion Code - Idle Speed Control System RPM Lower Than Expected
Quick Answer
The Powertrain Control Module (PCM) controls the engine idle speed to a specified level through the fine adjustment of the air, which is let into the intake manifold, by operating the Electronic Throttle Actuator Control (TAC). Common causes include Intake air restriction, Vacuum leaks, Dirty Throttle Body. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0506 2007 Ford Fusion Description
The PCM controls the Electronic Throttle Actuator Control so that the engine speed coincides with the target value memorized in the PCM. The target engine speed is the lowest speed at which the engine can operate steadily. The optimum value stored in the PCM is determined by taking into consideration various engine conditions, such as during warming up, deceleration, and engine load (air conditioner, power steering, and cooling fan operation, etc.).
The Diagnostic Trouble Code (DTC) will set the idle speed is less than the target idle speed by 100 rpm or more.
What are the Possible Causes of the DTC P0506 2007 Ford Fusion?
- Intake air restriction
- Vacuum leaks
- Dirty Throttle Body
- Faulty Electronic Throttle Actuator Control (TAC)
- Electronic Throttle Actuator Control harness is open or shorted
- Electronic Throttle Actuator Control circuit poor electrical connection
- Faulty Powertrain Control Module (PCM)
