The EGR solenoid Code 32 has come back to visit a few times. It has not been consistant in any way. It always happened during a long drive but the next time I would start it up, the light would be out.

I decided that it might be caused by a slight vacuum leak in the unit. Maybe temperatures or humidity or vibration would trigger the code. I got a brilliant idea to fix any slight leaks, I PLASTI-DIPPED the solenoid! I used the spray-on kind instead of the actual dip. Got a nice thick coat all over the little jumper hoses and into all the cracks, nooks, and crannies.

I have driven about 400 miles since then and so far, the code has not come back. It is a cheap fix that is worth a try!



Okay, I made my comment before I actually read this. Wow! I'm going to give it a try. And I work for Rustoleum, so I'm sure I can get my hands on a dented can of plastic dip for free!

Yep! So far, I'm code free! Be sure to post if it helps. Always good to know if a procedure is another good solution or just a fluke.

Will do. Tell me, did you just think of it on a whim?

Yep, it just came to me. To the best of my knowledge, it is a completely original thought.

Still putting on 100 miles a day. Still no codes!

That's great! I'm going to try it and post my results here. But I also may need to replace my vacuum harness. It's getting pretty raggedy.

Well, I sprayed the solenoid with plasti-dip (Rust-Oleum brand Flexi-Dip, actually), and no luck. It looks good, though! I'm going to order the stainless steel vacuum harness from TFS along with some other goodies, so that should probably do the trick.

Update: The CE light comes on a lot less now. The only other thing I did was reset the timing (it had too much advance).

now let�s look at the real thing


testing the solenoid�
looking at the assembly like this
The upper two connections are for the vacuum sensor
and the lower two are to drive the solenoid.


first I removed the short hose from the solenoid to the vacuum sensor
then pried the vacuum sensor and the connection block out of the bracket.
if you remove the solenoid from the bracket, be careful not to break off the fitting pointing sideways


removed two screws that hold the connection block and vacuum sensor together.
Now you can see what is left of a 20 year old foam filter.



I used a $3.00 meter from harbor freight for the testing, so any meter can do this�
Check the vacuum sensor without vacuum.
It should be an open circuit, or infinite resistance.



on the 3 sensors that I tested, they all showed continuity around 5� of mercury vacuum



then I tested for continuity in the windings of the solenoid.
** the readings were all over the place. From very high resistance to almost no resistance. This would back up pauls statement,





I have had the code 32 at steady highway speeds. I replaced the systems rubber vac hoses and the EGR tube with a new one. I took apart the solenoid and it looks almost brand new, with no breaks or corrosion in the copper. However, I still throw the code.

I measured the resistance and I am getting 0.393 megaohms on the vacuum sensor terminals of the solenoid and 93 Kohms on the solenoid terminals. With these readings, could the solenoid be faulty?

I don't think so.
Did you replace the ECM temp sensor?
And I don't mean the temp sensor for the fan.

Yes, I just replaced the ECM temp sender this afternoon and the code 32 still pops up. My EGR valve itself is original with 72K on it, but it moves up and down smoothly when removed from the car. The gaskets for it are new.

This code 32 is the only problem the car has and I hate to sell it with it still existing.
