Ignition Coil (2.5L)
On 2.5L, a single ignition coil is used. Coil is constructed of epoxy-embedded windings and is not oil filled. Battery voltage is supplied to ignition coil positive terminal from ASD relay. PCM receives inputs from appropriate sensors. Based on these inputs, PCM then determines the proper ignition timing and interrupts the ignition coil ground signal to trigger secondary voltage of ignition coil.
