Code 12 Egr.
My engine light is reporting code 12 (EGR). Im assuming that its referring to the control device, and valve assembly, and not the part that is on my intake manifold. Is this correct?

I started a thread in the accord forum
https://www.honda-acura.net/forums/s...d.php?t=173029
Im hunting here now to try to find some kind of answer.
Does it make a difference if the egr valve(prelude) being controlled by the (accord) egr soleniod ??
I've been looking at other accord h22a pics but its hard to see exactly how there set up.

I found this guys post @ honda-tech.com I haven't had the code come on for 2 days and I hope it stays off. I prob am going to try a couple things like this guy says below
I need help with this god awful code 12 (EGR) I have been getting. I checked all the wiring I have continuity to all wires.
EGR control solenoid
A25 power
A11 ecu trigger
EGR valve
A25 power
D12 ecu trigger
D22 ground
All vacuum lines are correct the EGR port on the intake manifold is recently cleaned.
I have tested the EGR valve by applying 8 in Hg of vacuum. The valve holds vacuum and the car stalls when the vacuum is applied. I have tried road testing the car with a vacuum pump/ gauge attached to the lower port on the egr control solenoid (#16 hose) the one that goes to the EGR valve. The solenoid works and sends vacuum over to the EGR valve. I am reading around 6 in Hg of vacuum while doing this road test. I have directly jumped the egr control solenoid with power from the battery on one lead and a ground on the other. With all vacuum lines connected. During this test I can physically see the EGR valve lift when I ground the solenoid. I am reading around 6 in Hg vacuum during this test. I have even tested the CVC valve it seems to be ok also matching its recomended vacuum in the Helms manual. The only thing I can think of is one or both the EGR control solenoid and EGR valve itself are bad. The EGR control solenoid is suppose to have around 8 in Hg of vacuum. During all the test I tried I only noticed around 6 in Hg of vacuum. I tested a friends car old Accord with EGR no codes his car also only read about 6 in Hg of vacuum. Someone give me so new ideas I need help. My registration is past due and I need to take this thing to the
