Canister Purge Control Valve: Testing and Inspection

2UZ-FE EMISSION CONTROL: PURGE VALVE:

INSPECTION

1. INSPECT PURGE VSV






(a) Inspect the VSV for open circuit.
(1) Using an ohmmeter, check resistance between the terminals.
Standard resistance:
26 to 30 Ohms at 20°C (68°F)
If the resistance is not as specified, replace the VSV.






(b) Inspect the VSV for ground.
(1) Using an ohmmeter, check that there is no continuity between each terminal and the body.
If there is continuity, replace the VSV.
(c) Inspect the VSV operation.





(1) Check that air does not flow from ports.





(2) Apply battery positive voltage across the terminals.
(3) Check that air flows from ports.
If operation is not as specified, replace the VSV.
