Help! Lights came on, What does it mean?

Hey,
I have a 2001 Cavalier 2.2L auto. with about 67k on it. While i was driving this morning, My Service, ABS, and Traction OFF Lights came on. Also my brake pedal got stiffer. Does anyone know what is goin on here?

Thanks,

Paul

Having the same problem with my 2000. just the other day and tryin to figure this out myself. If ya fing anything out please post.

I had this problem on a 2001. For me it was an anti-lock brake sensor. And if your abs light stays on, I don't think your anti-lock will work.

I have a 99 2.4 T with the exact same problem. My odometer doesn't work also and my tach jumps in and out from working. I also have 67K, what's up with these cars? It's been in the family since there was plastic on the seats and it's been nothing but a headache. Mine burns oil like crazy too, about 2 quarts/ 3000 miles.

My ABS, Trac Off, and ETS Off lights have also come one in my 98 z24 as well, I can't explain it.
