Code C200B Mercury Description

The Power Steering Control Module (PSCM) monitors various inputs and outputs of the Electric Power-Assisted Steering (EPAS) system in order to keep the system operating at peak capacity. Information provided by sensors (steering torque, vehicle speed, vehicle travel distance, etc.) are all compared to programmed and learned information. Likewise, outputs like the motor and steering rack (travel) are tested against programmed and learned information. The Diagnostic Trouble Code (DTC) will set when the PSCM detects a Steering Shaft Torque Sensor 1 Failure.
