P0431 is Warm Up Catalyst Efficiency Below Threshold (Bank 2). What is happening is this....the O2 sensor downstream of the Catalytic Converter is detecting the Converter is not working as efficiently as it should be (according to your cars specifications). 3 main causes of this is 1.) Defective O2 Sensor (which in your case elminates this one) 2.) Catalytic Converter is no longer functioning properly. or 3.) There is an exhaust leak. You will not notice any driveablitiy problems, however, you may get a rough/hard idle when its cold out. I would take your car to an exhaust shop and have them do a free exhaust system inspection. Alot of places like Midas/Mieneke Car Center/Monroe Muffler to name a few do these checks for free. Thanks for Using FixYa!

If it is a 2.2 Auto it has a VT25E Trans,A really bad experiment from G.M.There is no dipstick.The only way to check it per service is to remove the center part of the main drain plug while running in park,if fluid drains or trickles out they say it's full.You probally have other Issues inside the trans.Check your mileage they have a special coverage period for this Trans through Saturn Dealer!! They May cover it or do a partial coverage for you.Hope this helps
