Electronic Ignition (EI) System
WARNING: This page is about a different car, the 2003 Ford RV Cutaway, 2003 Ford Econoline, 2003 Ford E550 Super Duty, 2003 Ford E450 Super Duty, and 2003 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
The electronic ignition (EI) consists of a crankshaft position sensor, two four tower ignition coils and the powertrain control module (PCM). The ignition control module operates by sending crankshaft position information from the crankshaft position sensor to the ignition control module. The ignition control module generates a profile ignition pickup (PIP) signal (engine rpm) and sends it to the PCM. The PIP signal is one of the inputs that the PCM uses to determine transmission strategy, wide-open throttle (WOT) shift control, torque converter clutch control and EPC pressure.
