ENGINE CONTROL SYSTEM
IGNITION CONTROL SYSTEM
OUTLINE Sensors at specific points on the engine monitor current engine conditions and send signals to the ECMBased on these signals, the ECM determines the optimum ignition timing and releases voltage to the ignition coils
Basic sensors MAP sensor: Informs ECM of intake manifold pressureCKP sensor: Informs ECM of engine speed and crankshaft angleCompensating sensors Cylinder temperature sensor: Informs ECM of cylinder temperatureThrottle position sensor: Informs ECM of throttle opening angleShift position sensor: Informs ECM of shift position and changeSwitch Ignition switch: Informs ECM of "START" signal
