The torque sensor is hard wired to the PSCM, thus no connector or circuit testing can be performed. If an intermittent malfunction is suspected with the torque sensor or the circuits to the torque sensor, replace the EPS assembly. Refer to Steering Column Replacement . The scan tool can be used to view the torque sensor value.
