EGR Control Solenoid: Testing and Inspection
1. Unplug solenoid electrical connector.
2. Connect a 12 volt source to 1 of the solenoid terminals.
3. Connect & disconnect a ground to the other solenoid terminal.
If the solenoid clicks each time the ground is provided, the solenoid is operating properly.
If the solenoid does not click when the ground is provided, the solenoid is not operating correctly & should be replaced.
