Code P0320 2009 Ford Fusion Description

The P0320 code for a 2009 Ford Fusion indicates an issue with the Ignition/Distributor Engine Speed Input Circuit. This code is triggered when the Engine Control Module (ECM) detects a malfunction in the circuit that provides information about the engine speed to the ECM. The engine speed input is crucial for the ECM to control ignition timing and fuel injection accurately. When this circuit malfunctions, it can lead to poor engine performance, misfires, and potentially even engine stalling.
