Power Steering VSV

Disconnect VSV connector and check resistance between terminals. If resistance is not 33-39 ohms, replace VSV. If resistance is 33-39 ohms, disconnect vacuum hoses from 3-way joints. Blow into top hose. Air should not come out of other hose. With 12 volts and ground applied to terminals, blow into top hose. Air should pass through hoses. If results are not as described, replace VSV.
