Electronic Engine Controls – 2.5L Duratec-HE (122kW/165PS) 303-14A-5 303-14A-5 - MI4 DESCRIPTION AND OPERATION 5 4 3 E131881 Item Description 1 Camshaft position (CMP) sensor 2 Engine oil pressure (EOP) sensor 3 Knock (KS) sensor System Operation Ignition Coil E135520 The electronic ignition system is a fully electronic, distributor less ignition system with no moving parts on the high-voltage side 1 2 Item Description 4 Injectors 5 Variable camshaft timing (VCT) oil control solenoid The electronic ignition system is integrated into the PCM. With an electronic ignition system, high-voltage distribution to the individual cylinders is realized via special double spark coils. The signal from the CKP sensor forms the basis for ignition timing calculations. From an ignition map, the PCM determines the optimum closing time and current rise of the primary current circuit of the ignition coil with switching carried out via end-stages in the PCM. The ignition timing is determined by the PCM on the basis of the engine operating conditions. Once the ignition timing is determined, the PCM interrupts the current supply to the ignition coil
