Sprung a code, any ideas?

[DJ Taso]

My S.E.S. light's been going on and off for the past month and it's been buggin' the hell outta me so on the way home I had it scanned at the place that does most of the work on my car.

The scanner read, "Error 32 EGR Failure."

They told me it was exhaust relaited...something about a solyniod or something... Any ideas?

The EGR valve and the tube have too much carbon built up in them. You'll have to take the valve off and clean it and clean the tube going to it. The dealership has a machine to do it. It cost about $150 to get them to clean it out.

Hey DJ, this might help you.

Downloaded your latest, sounds good man.

Hope the above link helps. God bless The Rob

Here's a cut and paste from my response to a post on another forum:

That code indicates that when the PCM cycles the EGR valve, it doesn't see the expected change in the manifold absolute pressure (MAP) sensor reading. That means there's not enough EGR flow.

Could be a problem with low backpressure in the exhaust system (is your exhaust modified - no cats, efficient headers, cutout, etc?).

Could be a problem with the exhaust gas passages being plugged with carbon. You can remove the EGR valve and clean the pintle, and check the opening in the back of the intake manifold for carbon buildup.

Could be that the vacuum circuit is not providing sufficient vacuum to open the valve all the way. Check for broken vacuum lines from the intake manifold port to the EGR valve.

Could be the EGR valve is not opening. When you have it off to clean it, check the valve by putting a vacuum pump on the vacuum connection and verifying the pintle moves.

Mine is doing the same thing, do you mean like a Hoover or should I use something stronger like the 8 Pound Oreck XL?

You need a vacuum pump, like a "Mit-E-Vac".... a little handheld pump that pulls the air out of the EGR valve diaphragm chamber. It has to be able to pull at least 20"Hg of vacuum, to match what the intake manifold can operate at. With the EGR valve still on the car, you could just let your engine idle, and connect the EGR vacuum connection directly to the intake manifold vacuum nipple, bypassing the EGR solenoid. The valve should open, and the engine should run rough enough to stall.

LOL, I was just joking Injuneer, but I guess you have heard some silly questions like that before cuz you surely didn't catch on!!!!!!
Funny Stuff.

I actually tried to figure out whether you intended it as a joke or whether you were really asking for help. I erred on the side of offering help.

I guess I still don't get it but I've learned my lesson.
