Fault Code PO 141(1/2 O2 sensor relay)

HELP
My 2001 X-5 3.0 with 106.000mi. run fine but the ckeck engine light comes on and off frequently. I can't get it thru inspection till corrected, put my scan gauge on and got the PO 141 code (1/2 oxygen sensor relay reading.) I don't know where the relay is located so I can replace it also can it be the sensor itself? Any help appreciated.
