F 350 4WD Pickup V8-7.3L DSL (1988)
Canister Purge Solenoid
CANISTER PURGE SOLENOID (CANP) - Electrical solenoid or its control line. Solenoid opens valve from fuel vapor canister line to intake manifold
when energized. Controls flow of vapors between carburetor bowl vent and carbon canister.
CARBON MONOXIDE - A colorless, odorless, poisonous gas, composed of carbon and oxygen, that is a component of auto exhaust emissions.
Abbreviation is CO.
CAS - Cleaner Air System.
CATALYST - A compound or substance which can speed up or slow down the reaction of other substances without being consumed itself. In an
automatic catalytic converter special metals (i.e., platinum, palladium) are used to promote more complete combustion of unburned hydrocarbons and a
reduction of carbon monoxide.
CATALYTIC CONVERTER (CC) - A mufflerlike component in the exhaust system that promotes a chemical reaction that converts certain air
pollutants in the exhaust gases into harmless substances.
CHECK ENGINE LIGHT (CEL) - A dash panel light used either to aid in the identification and diagnosis of the EEC system problems or to indicate
that maintenance is required on non-EEC equipped vehicles.
CHECK VALVE - A one-way valve which allows a liquid or gas to flow in one direction only - prevents backflow.
CLOSED LOOP MODE - Mode in which the ECA operates with EGO sensor feedback.
Closed Crankcase Emission System
CLOSED SYSTEM - Crankcase ventilation system which vents crankcase pressure and vapors back into the engine where it is burned during
combustion rather than venting to the atmosphere.
CLOSED THROTTLE MODE - Mode in which the ECA varies the pulses width input of the fuel injectors and obtains the desired air/fuel mixture.
Many input sensors are used by the ECA in this mode.
COASTING RICHER SOLENOID VALVE (Courier) - Adds additional fuel to a lean mixture caused by deceleration. Controlled by accelerator and
speedometer switch.
COLD START SPARK ADVANCE SYSTEM (CSSA) - Added to the distributor spark control on some engines. System momentarily traps spark port
vacuum on the distributor spark advance diaphragm when engine coolant temperature is below 53~C (128~F). Used in conjunction with a DRCV and a
CSSA PVS.
COLD START SPARK HOLD SYSTEM (CSSH) - Provides improved cold engine acceleration. When engine coolant is less than 53~C (128~F) the
CSSH PVS is closed and the distributor vacuum signal travels through a restrictor providing a modified vacuum advance during the initial stage of
acceleration.
