DTC Trigger
WARNING: This page is about a different car, the 2020 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
This DTC sets if the sum of the 2 steering shaft torque sensors do not equal a specified voltage level. This can occur if the wiring harness is damaged, chewed, or the connectors are loose or damaged. An internal steering gear or PSCM fault can also cause this DTC to set. For additional fault setting information, refer to the PSCM DTC Chart.
