| 2. | Refer to CAMSHAFT POSITION (CMP) SENSOR . |
| 3. | Refer to IGNITION CAPACITOR . |
| 4. | Refer to IGNITION COIL . |
| 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 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, CMP sensors, and the Crankshaft Position (CKP) sensor. Refer to FUEL SYSTEM, DESCRIPTION AND OPERATION . The coil on plug ignition system utilizes an ignition coil for every cylinder. The ignition coils are mounted directly over the each spark plug.
