Question about 1999 Hyundai Accent
There is a purge solenoid for the EVAP system and it is item no.# 1 shown in the diagram below. You have to follow the purge valve vacumn hose to find the charcoal cannister if you need to inspect.
I have included a description of the EVAP system for your understanding.
EVAPORATIVE EMISSION (EVAP) CONTROL SYSTEM
The EVAP and on-board refueling vapor recovery (ORVR) system consists of a fill vent valve, fuel shut-off valve, fuel cut (roll-over) valve, fuel liquid/vapor separator, EVAP canister, EVAP canister purge solenoid valve, EVAP canister close valve, vacuum relief filler cap, and connecting lines and hoses. ORVR system is designed to prevent the release of fuel vapors during refueling. During refueling, as fuel enters the fuel tank, a vacuum is created in filler pipe, drawing air into the filler pipe and tank. Fuel vapor in fuel tank is then forced to the EVAP canister via the fill vent valve and the fuel liquid/vapor separator. A fuel tank pressure sensor is used for detecting EVAP system leaks by comparing pressures inside and outside of fuel tank.
EVAP Canister Purge Solenoid Valve
Fuel vapors are vented into the EVAP canister during refueling and when ignition is off. When engine is at normal operating temperature and engine speed is greater than idle, a thermovalve opens and allows vacuum to open the purge control valve. Canister vapors are then drawn into the intake manifold for burning during combustion. The purge control valve is kept closed during idle and engine warm-up to reduce HC and CO emissions.

Damaged harness. Inspect the wiring harness for damage. If the harness appears to be OK, disconnect the PCM, turn the ignition ON and observe a voltmeter connected to the EVAP Canister Purge solenoid driver circuit at the PCM harness connector while moving connectors and wiring harnesses related to the EVAP Canister Purge solenoid. A change in voltage will indicate the location of the fault.
