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 sensor signals do not equal a specified voltage level. This can occur if the wiring harness along the top of the EPAS gear is damaged, the electrical connectors are loose, damaged or corroded, or due to an internal fault in the steering gear. For additional fault setting information, refer to the PSCM DTC Chart.
