1NZ-FXE EMISSION CONTROL: PURGE FLOW SWITCHING VALVE: INSPECTION

INSPECTION

1. INSPECT PRESSURE SWITCHING VALVE





(a) Inspect the resistance.
(1) Measure the resistance between the terminals.
Standard resistance:





- If the result is not as specified, replace the pressure switching valve.

(b) Check the ventilation.




(1) Check that there is no ventilation from port E to port F.
If there is ventilation, replace the pressure switching valve.




(2) Apply battery voltage across the terminals.
(3) Check that there is ventilation from port F when air is applied to port G.
If there is no ventilation, replace the pressure switching valve.
