DTC P193B: Throttle/Pedal Signal: Description
WARNING: This page is about a different car, the 2018 Lincoln MKC. However, it is still accessible from the selected car via links, so may be relevant.
This DTC sets in continuous memory and on-demand when the information in the accelerator pedal position message from the PCM is "faulted" instead of "OK". This indicates a concern with the accelerator pedal sensor, wiring or PCM.
