DTC codes / Ford codes / P1141
P1141 on Ford vehicles indicates that the powertrain control module (PCM) has detected an abnormal signal from the fuel restriction indicator circuit, which typically monitors a fuel pressure switch or sensor in the fuel system. The PCM expects a specific voltage or state change when fuel flow is unrestricted, and it flags this code when the signal stays out of range or fails to toggle as expected.
Guidance is general and written for Ford vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
