I have a 95 Altima. I tested the EGR solenoid valve by using a multimeter. Disconnect the two-wire connector that plugs into the solenoid valve. When engine is cold and ignition turned on the two wires from the harness should read 12volts. Momentarily touch the connector to the socket on the solenoid valve and you should hear an audible click as the solenoid valve snaps open and closed. Also you can check the continuity of the solenoid valve coil. It should show good continuity and not "open." If you can read ohms on your meter you can also check the coil and it should read about 50 ohms if it is good. I was getting a P1400 code and thought my solenoid valve might be bad. It tested good so I removed the EGR valve and found it to be carboned up. A little choke cleaner fixed it up. Also the metal return tube that goes to the exhaust manifold was also carboned up. So far this has cured my problem.
It means something is not right with the car's EGR valve.These are possible causes, starting with the most common.Bad EGR solenoidExcessive resistance in control circuit (PCM controlled ground) due to an open, chafing or damage to the harnessPoor connection at the EGR solenoid harness (worn or loose pins)Water intrusion at the EGR solenoid harnessBlockage in EGR control solenoid holding solenoid open or closed causing excessive resistanceLoss of supply voltage to EGR solenoid
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).
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.
this is likely the solenoid that controls the egr. follow the tiny hose attached to the egr back to a small electrical solenoid. that part is best bought at a junkyard if possible because it is expensive new.

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.
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.
P0400 - Exhaust Gas Recirculation Flow Malfunction Possible causes - Exhaust Gas Recirculation (EGR) solenoid valve harness is open or shorted - Exhaust Gas Recirculation (EGR) solenoid valve circuit poor electrical connection - Exhaust Gas Recirculation (EGR) volume control valve stuck closed - Faulty Exhaust Gas Recirculation (EGR) volume control solenoid valve - Dead (Weak) battery - Faulty EGR temperature sensor and circuit - Faulty EGR Valve
It's inside the transducer. The black solenoid that's attached to the egr valve by two vac lines. 3.9L and 5.2L have a power plug and 2.5L isn't powered.
The EGR valve is located on the top of the intake manifold rearward of the throttle crank under the cowl. If you suspect a problem with the system, you may want to check the EGR control solenoid, the EGR control backpressure transducer and all vacuum hoses.
On the egr valve.
