Ignition Coil: Description
The engines are equipped with a coil on plug ignition system (Fig 1 ) or (Fig 2 ). Each cylinder has a dedicated coil that sits atop each plug. No secondary wires are required and connection from the coil to plug is made with a boot that is attached to the coil. The combination of the coil, boot, and fasteners is known as the ignition coil assembly. The Powertrain Control Module (PCM) determines which coil to charge and fire at the correct time.
