INPUT/OUTPUT SIGNAL CHART

*1: ECM determines the start signal status by the signals of engine speed and battery voltage.
*2: This signal is sent to the ECM via the CAN communication line.

SYSTEM DESCRIPTION

The evaporative emission system is used to reduce hydrocarbons emitted into the atmosphere from the fuel

system. This reduction of hydrocarbons is accomplished by activated charcoals in the EVAP canister.

The fuel vapor in the sealed fuel tank is led into the EVAP canister which contains activated carbon and the

vapor is stored there when the engine is not operating or when refueling to the fuel tank.

The vapor in the EVAP canister is purged by the air via the purge line to the intake manifold when the engine

is operating. EVAP canister purge volume control solenoid valve is controlled by ECM. When the engine oper-

ates, the flow rate of vapor controlled by EVAP canister purge volume control solenoid valve is proportionally

regulated as the air flow increases.
