P1870

I have a 1996 Buick Regal GS with a code P1870. I heard there was a bulletin that says that the valve body needs to be replaced on this vehicle. Are there any checks that I can do before I bring it top the shop?

Steve Says,

Thanks for asking me your question. There indeed was a bulletin for this code but I'm not sure if your vehicle is included in the bulletin. You will have to take it to your local dealer to find that out. You can also ask the question in the blue box on my questions page and find the answer there.

You can try replacing the filter if you want but most likely there will be nothing you can do.
