EVAPORATIVE EMISSION PURGE SOLENOID CHECK
 
 
 
 
1. Disconnect the vacuum hose ("R" mark stamp, "W" mark stamp) from the evaporative emission (EVAP) purge solenoid.
noteWhen disconnecting the vacuum hose, always place an identification mark so that it can be reconnected at its original position.
2. Disconnect the harness connector.
3. Connect a hand vacuum pump to nipple (A) of the EVAP purge solenoid (refer to the illustration at left).
4. As described in the chart below, check airtightness by applying a vacuum with voltage applied directly from the battery to the EVAP purge solenoid valve and without applying voltage.

ConnectedOpenedNegative pressure leaks
ClosedNegative pressure maintained
DisconnectedOpenedNegative pressure maintained
5. Measure the resistance between the terminals of the EVAP purge solenoid.
Standard value: 30 - 34 ohm [at 20°C (68°F)]
6. Replace the solenoid if airtightness or resistance is out of specification.
