Engine Identification (ID) Codes
WARNING: This page is about a different car, the 1995 Ford Pickup, 1995 Ford Econoline, 1995 Ford Club Wagon, and 1995 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
Engine ID codes are issued at beginning of KOER SELF-TEST. Codes are one-digit numbers represented by number of pulses displayed. See Figure. Engine ID code is equal to one-half the number o f engine cylinders. For example, 2 pulses would indicate that engine is a 4-cylinder. Engine ID code is used to verify proper PCM is installed and that SELF-TEST has been entered.
