Having problems with your 2002 Buick Century ?
I have a 2002 buick century that the service engine light and trac light and disc break light comes on and off. I can shut my car off and restart it and it will stay off for maybe 10 or 15 mins and then sometimes will come right back on. I have new breaks and rooters on the front and this did not seem to help.
I had the same problem and found out it was a bad electrical connection on both front wheels for the ABS sensors. It seems the contact pins in the connector are so small that they fail easily. Disconnect them, spray contact cleaner on both ends, then reconnect them. I took them apart and put them back together several times to insure good contact. Should solve the problem unless something else is involved. Good luck!
