EC-22 < SYSTEM DESCRIPTION > [HR16DE] COMPONENT PARTS <Reference data> *: These data are reference values and are measured between ECM terminals. EVAP Canister Purge Volume Control Solenoid Valve INFOID:0000000009020584 The EVAP canister purge volume control solenoid valve uses a ON/ OFF duty to control the flow rate of fuel vapor from the EVAP canis- ter. The EVAP canister purge volume control solenoid valve is moved by ON/OFF pulses from the ECM. The longer the ON pulse, the greater the amount of fuel vapor that will flow through the valve. EVAP Canister Vent Control Valve INFOID:0000000009020585 The EVAP canister vent control valve is located on the EVAP canis- ter and is used to seal the canister vent. This solenoid valve responds to signals from the ECM. When the ECM sends an ON signal, the coil in the solenoid valve is energized. A plunger will then move to seal the canister vent. The ability to seal the vent is necessary for the on board diagnosis of other evaporative emission control system components. This solenoid valve is used only for diagnosis, and usually remains opened. When the vent is closed, under normal purge conditions, the evapo- rative emission control system is depressurized and allows “EVAP Control System” diagnosis. EVAP Control System Pressure Sensor INFOID:0000000009020586 The EVAP control system pressure sensor detects pressure in the purge line. The sensor output voltage to the ECM increases as pres- sure increases.
