SOURCE: Where is the egr valve in a buick le sabre

The EGR Valve on this 3.8 L engine should be in front of the throttle body on the drivers side of the engine just to the right of the front valve cover. If you locate where the intake tube/duct attaches to the throttle body and then move just a few inches toward the front of the car it should sit right in that spot. It will have two bolts attaching it to the intake/tube. Hope you find it!!

The EGR, or exhaust gas recirculation valve, takes inert exhaust gasses drawn from the exhaust system and reintroduces them into the combustion chamber through the intake manifold. This process lowers the peak combustion temperature and helps combat the formation of Nitrous Oxide (NOx) in the exhaust.

  1. Separate the intake ducts from the air cleaner assembly by loosening the retaining clamps and pulling the ducts away from the housing.
  2. Disconnect the vacuum line from the air cleaner assembly.
  3. Remove the wing nut that secures the air cleaner housing lid to the base.
  4. Remove both the air cleaner hosing lid and base.
  5. Locate the EGR valve. Look at the front of intake manifold. The EGR valve will be bolted to the intake manifold just in front of the carburetor.
I hope help you with this. Good luck.

SOURCE: 1992 Buick LaSabre. Where is the EGR valve?

I also have a 92 Lesabre. I couldn't find the EGR valve either, so I asked the dealer where it is. They looked up the part and were surprised to discover the 92 Buick Lesabre did not come with an EGR valve. It's hard to believe, but you can verify it by calling the dealer and asking them to look up the part. It doesn't exist. Apparently, the 92 was the only year the Lesabre was manufactured with no EGR valve.

My 1989 Buick lasabre had a bad idle and when I put it in drive it drives good until 30 mph but after that it Boggs out like it has no power


It could be a bad diaphragm in your EGR valve. They often used ported vacuum and if there is a leak it won't show up until you are at higher rpms. A quick check is to remove the vacuum line from the EGR and plug it. Retest and see if the issue resolves itself. If so, replace the EGR valve.

The biggest cause of engine bogging is low intake vacuum and a bad EGR valve can do it easily.

What would be the first and most likely reason for my 1997 buick lesabre to be giving me a egr pintle position circuit malfunction?


This code indicates a problem with the EGR valve's pintle position. The EGR Valve's pintle could just be stuck in which case the problem could be fixed by cleaning the EGR valve.

If the EGR valve is electronically controlled or cleaning the valve does not fix the problem, you will most likely have to replace the EGR Valve.

Keep in mind that the EGR valve relies on inputs from other sensors to determine the pintle position. If one of these other sensors is not operating correctly, it could be giving you a false P1406 error code.

1992 Buick LaSabre. Where is the EGR valve?


The EGR valve may have a protective cover on it:

After removing the cover, the egr valve is beneath, you will need to remove retaining clips to remove the egr valve.

Try cleaning your grounds under the hood: under Ignition Module bracket, rf fender behind battery and lf fender in front of windshield washer fluid bottle.
I had similar problem and this fixed it.....grounds are very important for computer.
I used a carbon conductive grease on the connections to keep them from oxidizing.
Hope this helps you out.

It sounds like you have a vacuum leak or intake gaskets leaking. Try this. Start the engine and let it reach the idle it want to go to. Get you a can of Brake Clean and spray it around the intake manifold (it on the top center of the engine, you may have to removed a plastic cover) If the engine idle changes up or down then the intake gaskets are leaking hence your vacuum leak. I hope this will help you.
