Canister Purge Volume Control Valve: Testing and Inspection
VSV For Canister Closed Valve (CCV)
VACUUM SWITCHING VALVE ASSY N0.1
a. Inspect VSV for Canister Closed valve (CCV).
1. Using an ohmmeter, check that there is continuity between the terminals.
Resistance: 25 - 30 Ohm at 20 °C (68 °F)
If there is no continuity, replace the VSV.
2. Using an ohmmeter, check that there is no continuity between each terminal and the body.
If there is continuity, replace the VSV.
3. Check that air flows from ports A to B.
4. Apply battery positive voltage across the terminals.
5. Check that air does not flow from ports A to B.
