EGR Solenoid

1999 F53 v10.

Our Rv is not running as it should, erratic tick over and does not seem as powerful as it used to. We put it on a Snapon Obd2 reader and it came up with the 02 sensors not reading on bank 1. We have purchased these.

Another part which we can not find on Rockauto is the EGR solinoid. The valve is listed, but not the solinoid. Is it known as something else, or where could we get one. But needs shipping to UK.

We checked the EGR and had sucking to the solinoid but nothing from the end which goes into the Valve. Checked valve it works.

Thanks for any Help

Why do you believe there is an EGR solenoid? I believe it is vacuum controlled on your model/year.

I think part of the problem is that the item you are looking for is not called a solenoid. A solenoid is something electrical and as you mentioned your egr has a "sucking" (vacuum) going to it, but nothing from the valve. Most vacuum diaphragm operated EGR valves come with the vacuum diaphragm to open and close the valve, you really shouldn't see the valve open at an idle, only when the vacuum is very strong (like when decelerating), not to mention, except for perhaps a computer check, a non-opening egr valve really isn't a problem that causes the engine to run bad, the primary problem is when it opens and stay open when it shouldn't (causes the engine to run bad). When EGR valves first came out, a lot of times they would stick open and many mechanics would simply create an EGR valve gasket out of an aluminum can to permanently seal the valve closed. Doing this didn't harm anything, but doing this didn't allow for as clean of emissions as the engine was designed for. ~CA

BTW, can you give more detail about the problem that leads you to believe the EGR valve is bad? If you want to test if the EGR valve is the problem, just remove it, cut a coke can gasket for it (strong scissors will work) and put it back on which would seal the EGR valve, and if it runs much better then replace the EGR valve because yours is sticking open.

Will take a photo in morning, so can identify the item.

As you can see by photos, the EGR vacuum goes to A Solenoid/Relay unit. It's the Solinoid/Relay which we are trying to find.

Our Rv. Fleetwood Bounder 34J. 1999. Briton v10.

So although RockAuto doesn't show one for the F53 of that year, I went to the listing for the F450 SuperDuty with V10 of that year, and found this.

which is very likely to be what you are looking for.

What mpaton and I shared a link to are the same item, so I think that is it and perhaps you can obtain one locally. Good Luck, ~CA

Thank you.
Will take ours off and see if any part numbers on it, to make sure. Is there a way to check them while it's off?

I believe the coil resistance is supposed to be between 26 and 40 ohms, so you can check that. It is essentially a vacuum valve that is closed when no voltage is applied, and fully open when it gets voltage (not sure how much, 5V or 12V). Thirdly, the way it's supposed to work is that it gets given pulses of voltage quite rapidly, so that if the voltage is applied 50% of the time, then the valve will be 50% open, that is how variable valve openings are achieved.


Usually the Ford tests and codes are fairly specific as to what the failure is. Did you get a code or codes?


And if you have a Ford specific scan tool, or the Forscan program you should be able to run some tests.

Only codes which came up were the O2 sensors, But it was running erratic unplugged the EGR and made no difference so wanted to check that part.
