Purge Control Solenoid Valve
- Disconnect vacuum hose and harness connector from purge control solenoid valve. Connect vacuum pump purge control solenoid. Apply vacuum and battery voltage and ground to solenoid. With battery voltage applied, vacuum should release. With battery voltage disconnected, vacuum should hold.
- Using an ohmmeter, measure resistance between solenoid valve terminals. At 68°F (20°C), resistance should be 26 ohms on Accent, Elantra and Tiburon, or 36-44 ohms on Sonata.
