EVAP Purge Solenoid Inspection

EVAPORATIVE EMISSION PURGE SOLENOID INSPECTION

NOTE: When disconnecting the vacuum hose, place an identification mark on it for proper re-connection.

1. Disconnect the vacuum hose from the solenoid valve.
2. Disconnect the harness connector.
3. Connect a hand vacuum pump to nipple (A) of the solenoid valve.
4. Check airtightness by applying a vacuum with voltage applied directly from the battery to the purge control solenoid valve.

Battery Voltage / Normal Condition.
Applied Vacuum Leaks
Not Applied Vacuum Maintained






5. Measure the resistance between the terminals of the solenoid valve.
- Standard value: 25-35 ohms [at 20°C (68°F)]
