The power steering control module receives voltage through circuits 838 (LG/VT) and 601 (LB/PK) and ground through circuit 57 (BK). The power steering control module sends power to the torque sensor through circuit 997 (BN/OG) and provides a ground path for the torque sensor through circuit 1221 (WH/OG). The power steering control module receives signals from the torque sensor through circuits 998 (YE/LG), 1572 (DG), and 1573 (YE) which is dependent upon the torque being requested by the steering input. The power steering control module sends varying amperage through circuits 3140 (BK) and 3141 (WH) dependent upon the desired output of the power steering control module.
