Replacement EGR Fitment

[RKTJeep]

I ordered a replacement EGR valve from Rockauto, but it is significantly different from the factory one (much larger diaphram). It came without the vacuum transducer and does not have a port to connect the original vacuum transducer. From the limited information I can find, it looks like the transducer interlocks the EGR operation to only open when there is exhaust pressure.

 

Has anyone ran this setup or similar EGR without the vacuum transducer?

You ordered the wrong EGR

Can you point me in a direction for the correct one?

53004867  is the part number , I don't see them come up very often though.

Perhaps it is a new design that eliminates the transducer by integrating it's function into the valve. Maybe that's why there are two holes in the body of the replacement EGR. Does it bolt up?

I bought one of these from NAPA a couple of years ago.  I don't remember paying this much then but we know how that goes.

********* UPDATE SOLVED *********

So the RockAuto replacement EGR caused it to fail California Emmissions for NO2. After some diagnosis, I found that the vacuum pressure was not enough to actuate the EGR properly. Luckily was able to to source the a used OEM EGR on the forum here, I couldn't find an EGR era 4.0 in the LA area salvage yards. It passed emissions at the very next test.

 

So if you have a used OEM EGR don't throw it away. You might want to post it up here for those in restricted areas. I haven't been able to find a new OEM equivalent, so we'll be dependent on salvage and community used parts as far as i can see.

Thanks for the update!
