Code P0505 2011 Ford Fusion Description

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). The operating of the throttle valve is varied to allow for optimum control of the engine idling speed. The PCM calculates the actual engine speed from the signals of the crankshaft position sensor (POS) and the camshaft position sensor.
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) sets when the desired RPM could not be reached or controlled during the key ON engine running (KOER) self-test.
