Integrated Electronic Ignition System
WARNING: This page does not describe the selected car, but rather 32 other vehicles, including the 2010 Mercury Milan, 2010 Mercury Mariner, 2010 Mercury Grand Marquis, 2010 Lincoln Town Car, and 2010 Lincoln Navigator L. However, it is still accessible from the selected car via links, so may be relevant.
The integrated electronic ignition system consists of a crankshaft position (CKP) sensor, coil pack(s), connecting wiring, and PCM. The coil on plug (COP) integrated electronic ignition system uses a separate coil for each spark plug and each coil is mounted directly onto the plug. The COP integrated electronic ignition system eliminates the need for spark plug wires but does require input from the camshaft position (CMP) sensor.
