Integrated Electronic Ignition System
WARNING: This page is about a different car, the 2005 Mazda Tribute. However, it is still accessible from the selected car via links, so may be relevant.
The Integrated Electronic Ignition (El) System consists of a crankshaft position (CKP) sensor, coil pack(s), connecting wire, and PCM. The Coil On Plug (COP) Integrated El System uses a separate coil for each spark plug and each coil is mounted directly onto the plug. The COP Integrated EI System eliminates the need for spark plug wires but does not require input from the camshaft position (CMP) sensor.
