P0001 Fuel Volume Control Circuit Open - 2013 Ford Focus Diagnosis and Fix
I'm experiencing a new issue with my 2013 Ford Focus: the vehicle starts and runs but responds poorly to the gas pedal. The check engine light is triggered with fault code P0001, indicating an open fuel volume control circuit. I've verified that there is battery-positive voltage at the sensor, but no ground signal is being received from the Powertrain Control Module (PCM). Despite checking connections and wiring, I'm unable to establish a proper ground. Any advice or troubleshooting steps for this specific P0001 code on a 2013 Ford Focus would be greatly appreciated.
The issue is likely with the fuel volume pressure sensor. Refer to bbbind.com for detailed wiring diagrams and schematics.
