Electronic Ignition (EI) System

The Electronic Ignition (EI) system consists of a Crankshaft Position (CKP) sensor, a pair of 4-tower ignition coils and the PCM. The ignition control module operates by sending CKP information from the CKP sensor to the ignition control module. The ignition control module generates a profile ignition pickup signal (engine rpm) and sends it to the PCM. The PCM uses the profile ignition pickup signal in the transmission strategy, Wide Open Throttle (WOT) shift control, TCC control and operating pressures.
