Canister Purge Solenoid: Testing and Inspection

INSPECTION

1. Check Vacuum Circuit Continuity In Vacuum Switching Valve (VSV) By Blowing Air Into Pipe





^ Connect the VSV terminals to the battery terminals as illustrated.
^ Blow air into pipe E and check that air comes out of pipe F.





^ Disconnect the battery from the VSV.
^ Blow air into pipe E and check that air does not come out of pipe F. If a problem is found, replace the VSV.

2. Check For Short Circuit





^ Using an ohmmeter, check that there is no continuity between the terminal and the VSV body. If there is continuity, replace the VSV.

3. Check For Open Circuit





^ Using an ohmmeter, measure the resistance between the terminals as shown.

Resistance: 27 - 33 Ohms at 20°C (68°F).

If resistance is not within specification, replace the VSV.
