Vapor Pressure Sensor: Testing and Inspection

CIRCUIT DESCRIPTION 

To reduce HC emissions, evaporated fuel from the fuel tank is routed through the charcoal canister to the intake manifold for combustion in the
cylinders.
The ECM changes the duty signal to the VSV for EVAP so that the intake quantity of HC emissions is appropriate for the driving conditions
(engine load, engine speed, vehicle speed, etc.) after the engine is warmed up.
