The ignition system is comprised of the following components:

1.	Refer to IGNITION COIL .
2.	Refer to CAMSHAFT POSITION (CMP) SENSOR .
3.	Refer to IGNITION CAPACITOR .
4.	Refer to KNOCK SENSOR .
5.	Refer to VARIABLE VALVE TIME (VVT) SOLENOIDS .
6.	Refer to POWERTRAIN CONTROL MODULE (PCM) .

OPERATION 

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 sensors, and the crankshaft position sensor. The coil on plug ignition system utilizes an ignition coil for every cylinder (coil over). The ignition coils are mounted directly over the each spark plug.
