How to test the Ford EGR valve EGR vacuum solenoid?
CASE 1: If the voltage reading on the multimeter increased as you applied vacuum with the vacuum pump and decreased when you released the vacuum, then the DPFE sensor is working correctly. The next step is to verify/check the EGR Valve Vacuum Regulator Solenoid. Go to: TEST 4: Testing The EGR Vacuum Regulator Solenoid (Part 1).
What does the solenoid do on an EGR battery?
The solenoid controls a rapid-deployment valve to regulate the flow of vacuum, through the ports, to the EGR valve. Blow forcefully through one of the hoses. Air should not pass through. If air cannot pass through, neither can vacuum and the valve is closing properly. Attach the loose jumper wire back on the battery.
What are the disadvantages of pneumatic EGR valves?
The disadvantages of the pneumatic EGR valves are: the closing is ensured only by a return spring (in the event of soot deposits on the valve, it is not possible to remove the deposit by fast valve closing/smashing, which can result in a permanent open position)
What kind of fuse to use on EGR solenoid?
Make a jumper wire with an in-line fuse holder and install a 10-amp fuse. Crimp each end of the fuse holder to a section of wire using crimp connectors. Make another jumper wire and attach both wires to the connectors on the solenoid.

How is the dpfe sensor connected to the EGR valve?
Basically, follow the EGR pipe until you see 2 metal tubes next to each other split off from it, then follow those to the rubber hoses and those hoses to the DPFE sensor. The EGR Actuator is an electric device that allows small amounts of vacuum pressure to pass on to the EGR Valve.

What’s the best way to clean an EGR valve?
Cleaning the Valve: After removing the valve, use an EGR valve cleaner, if possible. However, you can use carburetor cleaner or solvent as well. Apply the cleaner to the passages at the bottom of the valve, intake and exhaust passages. Use a dull scraper and wire brush to remove carbon deposits from the bottom of the valve, plunger and valve seat.
