  1. Measure the resistance according to the value(s) in the table below.

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    1 - 2
    		20°C (68°F)
    		23 to 26 Ω
    1 - Body ground
    		Always
    		10 MΩ or higher
    2 - Body ground
    		Always
    		10 MΩ or higher
    If the result is not as specified, replace the duty vacuum switching valve.


  1. Check operation of the purge VSV.
