The EGR on a 2007 is not vacuum controlled.
The EGR (Exhaust Gas Recirculation) valve opens when vacuum is applied. The EGR vacuum solenoid opens and closes the vacuum supply to the EGR valve when it is commanded to do so by the ECM (Engine Control Module).
Yes, the engine can still run with the EGR vacuum solenoid not in the working condition.
Plugged EGR passage which restricts the flow of exhaust gasses, faulty EGR solenoid, faulty EGR solenoid wiring/harness, vacuum lines damaged or disconnected to the EGR valve solenoid or to the EGR valve, or a faulty EGR valve.
Yes, the Diamante has an EGR solenoid. On any Mitsubishi, if the car has an egr valve, it has a solenoid to operate the valve. Just follow the vacuum line from the valve and it will go to the solenoid. There may be another one way valve between the valve and the solenoid, though. The solenoid is electronic.
EGR { Exhaust Gas Recirculation} Flow Malfunction Early Exhaust Gas Recirculation (EGR) systems components include and EGR Valve, and Engine Control Μodule (ECΜ) Controlled Vacuum Switch Valve or EGR Solenoid and an EGR Vacuum Μodulator. Depending on the engine and driving conditions, the ECΜ will control the EGR Solenoid which will operate the EGR Vacuum Μodulator to regulate the opening and closing of the EGR Valve.
egr solenoid is the most common problem. The EGR Solenoid has a vacuum hose at the top running from the EGR Valve and one vacuum hose that connects to the upper intake manifold. The solenoid is brown in color. Try replacing all of the vacuum hoses before anything first for only 3.00 this could fix your problem as well. (you have a vacuum diagram on your hood)
You can find the EGR Vacuum Solenoid for a 97 Ford Probe 2.0L at www.autopartswarehouse.com. You can also call them at 1-866-789-3624 or 1-801-214-2997.
EGR vacuum solenoid circuit fault
It is an electrically operated valve that when energized let's the vacuum through to the EGR valve to open it. Many also contain an electical switch that is closed when the vacuum is applied to the EGR valve to send a confirmation signal back to the ECM (engine control module).
