Diagnostic Aids
WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
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 in Steering Wheel and Column. The scan tool can be used to view the torque sensor value.
