DTC P193B: Throttle/Pedal Signal: Action
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 when the accelerator pedal position message sent from the PCM is "invalid" instead of the actual pedal position. RETRIEVE and REPAIR all non-network DTCs in the PCM. REFER to the appropriate Electronic Engine Controls article.
