DTC C0040 RF Wheel Speed Circuit Malfunction

I have a 2001 Grand Prix SE, 3.1 with DTC C0040. If I reset the code, it comes back. The RF wheel sensor appears to be OK. Does anybody have schematics or detailed instructions for troubleshooting this and/or wringing out the wiring? Also the wheel speed indicates 2 MPH on the other 3 wheels when I'm sitting still! Any suggestions?
Thanks
