General System Description

Electronic Ignition System Description:

Ignition Coil Cross Section:

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
^ Two ignition coil assemblies
^ The Crankshaft Position (CKP) Sensor
^ The Camshaft Position (CMP) Sensor
^ The spark plugs
^ The spark plug (secondary ignition) wires

The electronic ignition system provides the following benefits:
^ Improved ignition timing accuracy
^ Reduces high-voltage losses
^ Enhances 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.
