Question about 2002 Pontiac Grand Prix
The wheel sensors or wires to the wheel sensors are bad. there are some bad import parts out there that do not live up to the OEM products. that is why a warrenty is important. you should replace them in pairs ( both front or both rear). check the wiring/ sockets at the lower ball joint, make sure the sockets are securely attached with clips or wire ties and that the pins didn't bend over in the socket when you plugged them in,( make sure the wire does not touch any metal parts or it will wear into a short). if all connectors and wires are secure, unplug the connector and look at the pins in the socket, straighten them if bent and try pluging them in again, (you may need to clear the codes by disconnecting the battery) if the wire is good sockets are good my vote would be a bad wheel sensor whitch will force a bearing replacement if you want anti lock/ and traction control to work.
