Electronic Ignition (El) System
WARNING: This page is about a different variant/trim than selected.
The electronic ignition (El) system consists of the PCM, a crankshaft position (CKP) sensor and one multi-tower ignition coil. The CKP sensor sends a crankshaft position signal to the PCM. The PCM then sends the appropriate ignition signal to the ignition coil. The PCM uses this signal in the transaxle shift strategy, as well as TCC control and electronic pressure control. Wide open throttle (WOT) shift control is also affected by the El system input.
