Other than replacing the vacuum solenoid assembly or repairing a vacuum leak in one of the small line, what have you had go bad that caused a code 32?

I had a bad weather-pak pin (corroded) in the connector to the solenoid.......Paul

was the pin had too much build up on it to allow current flow, or was it all ate up?

Below the EGR there are 2 gaskets. One for the EGR to the adapter for the EGR tube and one below the adapter to mount it to the exhaust. The one on the exhaust side went bad causing a code 32.

and you didn't fix anything else?

Correct

In searching out the problem I took a 3 foot tube and put it up to my ear to listen for leaks. Keep coming back to the EGR because that area was the loudest. decided to take the EGR off to look at the EGR tube gasket. Once I had the EGR off I noticed the riser that the EGR tube bolts to was loss. Pulled it up and there it was. Only had 1/2 of the lower gasket.

Right next to the four pin connector, there is a short rubber hose going from the vacuum switch to the incomming vacuum. check this hose for a leak. code 32 is telling the ECM that there is no vacuum to the solenoid switch.

Thanks for mentioning that little hose.
from the reading i've done, a code 32 is telling you one of two things.
You do NOT have enough vacuum at the vacuum sensor when the computer wants the egr open
Or
You DO have too much vacuum at the vacuum sensor when the computer wants the egr to be closed.

That’s why I’m so curious about the leaking EGR gasket,
CC Rider, did you have a High idle problem as well or just the code 32

Only when engine was cold - once warmed up idle was back to normal but did sporadicly fluctuate

intersting.

i was pulling that 32 code as well mine was a short rubber hose going from the vacuum switch to the incomming vacuum, check this hose for a leak thats where mine was

thanks,
ka4nkf already mentioned that one.

I had a very small crack in my egr tube close to the plenum. Obviously not bad enough to cause a noticeable vacuum leak, but after cruising at 70mph for ten minutes or so it would throw a Code 32.

i believe you guys, it just doesn't make since to me.

Here's the aforementioned hose that can cause a Code 32.

anyone else wanna chime in?

The ECM only sees two aspects of the EGR system, the vacuum switch (on or off) and the solenoid coil. I don't know if the ECM checks the solenoid windings for shorts or opens, but I do know that it checks the vacuum switch for activation when the ECM commands EGR. The ECM won't command EGR at WOT or idle, only part-throttle cruise, so I suspect that the ECM only looks at the switch.

FWIW.

last chance before i'm finished with this thread.
