Section 707 (Ignition System (Service Information)): Description

WARNING: This page is about a different car, the 2020 Chrysler 300 and 2019 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

All engines use a fixed ignition timing system. Basic ignition timing is not adjustable. All spark advance is determined by the Powertrain Control Module (PCM).

The ignition system used on these engines is referred to as coil on plug. The system's four main components are the coils, spark plugs, Camshaft Position (CMP) sensors, and the Crankshaft Position sensor (CKP). The coil on plug ignition system utilizes an ignition coil for every cylinder. The ignition coils are mounted directly over the each spark plug.
