EGR Time Delay Solenoid 6-Cylinder And V8 Models

Make sure all vacuum hose connections are correct and not leaking.
Disconnect electrical plug from solenoid valve.
Connect either solenoid terminal to a ground and the other one to the battery positive terminal to activate the solenoid valve. This shuts off control vacuum to the EGR system.
NOTE: You should hear a "click" from the solenoid as it is connected to the battery positive terminal.
To test valve operation, let engine idle, then increase engine speed to about 2000 RPM. Watch EGR control valve stem, it should move. If not, replace the delay solenoid.
