Canister Purge Solenoid: Testing and Inspection

VACUUM SWITCHING VALVE (VSV) FOR EVAP INSPECTION

1. REMOVE V-BANK COVER
2. REMOVE VSV
(a) Disconnect the VSV connector
(b) Disconnect these hoses from the VSV:
- EVAP hose from throttle body
- EVAP hose from charcoal canister
(d) Remove the bolt and VSV from the intake chamber.
3. INSPECT VSV





A. Inspect VSV for open circuit
Using an ohmmeter, check that there is continuity between the terminals.

Resistance: At 20°C (68°F): 30 - 34 Ohms

If there is no continuity, replace the VSV.





B. Inspect VSV for ground
Using an ohmmeter, check that there is no continuity between each terminal and the body.
If there is continuity, replace the VSV.
C. Inspect VSV operation





(a) Check that the air flows with difficulty from port E to F.





(b) Apply battery voltage across the terminals.
(c) Check that the air flows without resistance from port E to F.
If operation is not as specified, replace the VSV.
4. REINSTALL VSV
(a) Install the VSV with the bolt.

Torque: 18 N.m (185 kgf.cm, 13 ft.lbf)

(b) Install the hose clamp to the VSV.
(c) Connect these hoses to the VSV:
- EVAP hose from throttle body
- EVAP hose from charcoal canister
(d) Connect the VSV connector.
5. REINSTALL V-BANK COVER
