Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Integrated Electronic Ignition System
Integrated Electronic Ignition (EI) System consists of a Crankshaft Position (CKP) sensor, coil pack(s), connecting wiring, and PCM. Coil On Plug (COP) Integrated EI System uses a separate coil for each spark plug and each coil is mounted directly onto plug. COP Integrated EI System eliminates the need for spark plug wires but does require input from Camshaft Position (CMP) sensor. For additional EI system information, see INTEGRATED ELECTRONIC IGNITION SYSTEM under IGNITION SYSTEMS.
