Description

The electronic ignition system consists of the following components:
• Engine Control Module (ECM)
• Ignition Coil
• Spark Plugs
• Spark Plug Wires
• Camshaft Position (CMP) Sensor
• Crankshaft Position (CKP) Sensor

Operation

The ignition system utilizes a split ignition coil which supplies secondary voltage to two cylinders. When the ignition
coil discharges, two spark plugs fire at the same time. The Engine Control Module (ECM) uses inputs from the
Crankshaft Position (CKP) Sensor to determine the Top Dead Center (TDC) position of the piston for cylinder number
one, and the Camshaft Position (CMP) Sensor to determine which ignition coil to energize.
