Ignition System: Description and Operation
GENERAL INFORMATIONThis engine uses a fixed ignition timing system.
Basic ignition timing is not adjustable. The Powertrain Control Module (PCM) determines spark advance. The system's main components are:
- Ignition Coil
- Distributor
- Crankshaft Position Sensor
- Camshaft Position Sensor
The crankshaft position sensor and camshaft position sensor are hall effect devices. The camshaft position sensor and crankshaft position sensor generate pulses that are inputs to the PCM. The PCM determines crankshaft position from these sensors. The PCM calculates injector sequence and ignition timing from crankshaft position.
