EGR Control Solenoid (2.5L)
Disconnect vacuum and electrical connections from solenoid. Apply low air pressure into EGR control solenoid port "A" and ensure air pressure does not flow through solenoid. See Fig 1. Using jumper wire, connect negative terminal to ground and apply 12 volts to positive terminal. Apply low air pressure to port "A" and ensure air pressure flows through port "B" of solenoid. Replace solenoid if it does not operate as specified.
