GLOSSARY OF TERMS AND ABBRREVIATIONS
CKT – Circuit.
CL – Closed Loop.
CLC – Converter Lock-up Clutch.
CO – Carbon Monoxide.
COC – Conventional Oxidation Catalyst.
COMPUTER TIMING –Total spark advance in degrees
before top dead center. Calculated by Ford EEC-IV processor,
based on sensor input.
CONTINUOUS SELF-TEST – Continuous test of Ford EEC-
IV system conducted whenever vehicle is in operation.
CPS – Crankshaft Position Sensor. Provides the ECU with
engine speed and crankshaft angle (position).

CURB IDLE – Computer controlled idle rpm.
CVR – Control Vacuum Regulator.
CWM – Cold Weather Modulator.
CYLINDER IDENTIFICATION SIGNAL (CID) – A signal
generated by crankshaft timing sensor, used to synchronize
ignition coils, due to the fact that some models use a 2 ignition
coil pack DIS system.
C 3 I – Computer Controlled Coil Ignition. Produces ignition
spark without aid of an ignition distributor.
