Evaporative system, it is a system meant to prevent the escape of petrol vapors from the fuel tank or
carburetor float bowl to the atmosphere while the engine is off. The vapors are stored in a canister or in the crankcase until is started. OBD-II, systems were designed to maintain low emissions of in use vehicles, including light and
medium duty vehicles. The OBD-II diagnostic system shall control the air flow of the complete evaporative system. In
addition, the diagnostic system shall also monitor the complete evaporative system for the emission of Hydrocarbon
vapor into the atmosphere by performing a pressure or vacuum check of the complete evaporate system. From time
to time, manufactures may occasionally turn off the evaporative purge system in order to carry out a check.
