Did you know that the typical V6 ignition system generates one hundred and fifty sparks per second at three thousand RPM? And that each spark event is precisely timed to within milliseconds? Your vehicles' ignition system operates using sophisticated computer controls. Sensors provide the engine management computer with crankshaft speed and position. The computer uses this information to accurately trigger the ignition coils. The Ignition coils generate a high voltage electrical pulse to form the ignition spark. The spark jumps the gap at the spark plugs, igniting the air/fuel mixture within the engine cylinders. Key components of the ignition system include: Crankshaft and Camshaft position sensors, Engine Control Module, Ignition Coils, Knock Sensors and Spark Plugs. Malfunctions can cause drivability concerns including an illuminated or flashing check engine light or even a no start condition. The ignition system contains high voltage
electrical energy; avoid touching ignition system components while the engine is running. In this short video you'll discover how electrical and ignition systems on your vehicle work.
