The electronic ignition system is of the Direct Ignition System (DIS) type and is controlled by the Powertrain Control Module (PCM). The electronic ignition system is composed of the following components:
^ The PCM
^ The 4 ignition coil assemblies
^ The Crankshaft Position (CKP) sensor
^ The Camshaft Position (CMP) sensor
^ The spark plugs

The electronic ignition system provides the following benefits:
^ Improved ignition timing accuracy
^ Reduced high-voltage losses
^ Enhanced overall ignition system reliability

The electronic ignition system components cannot be disassembled or repaired. A component that is correctly diagnosed as faulty must be replaced as a complete unit.
