Canister Purge Control Valve: Testing and Inspection

2GR-FE EMISSION CONTROL: PURGE VALVE: INSPECTION

INSPECTION

1. INSPECT VACUUM SWITCHING VALVE
(a) Check the VSV for an open circuit.




(1) Using an ohmmeter, measure the resistance between the terminals.
Standard resistance:






If the result is not as specified, replace the VSV.
(b) Check operation of the VSV.




(1) Check that air does not flow from the port as shown in the illustration.
If the result is not as specified, replace the VSV.
(2) Apply battery positive voltage across the terminals.




(3) Check that air flows from the port as shown in the illustration.
If the result is not as specified, replace the VSV.
