PRVR Control Solenoid Valve
- Remove vacuum lines and electrical connector from solenoid. Remove solenoid from vehicle. Using jumper wires, connect battery voltage and ground to solenoid connector terminals. Blow into vacuum port "B" on end of solenoid.
- As battery voltage is applied, air should pass out of vacuum port "A". With power and ground removed from solenoid, air should pass out of port "C". Port "C" may be covered by a filter. See Figure .
