J1939 code SPN 1076. Below — how the fault is worded at the factory by Ford Trucks, and what the second half of the code (FMI) means in the standard.
Ford Trucks/Ecotorq writes fault numbers in its own format: the code in the table below is a Ford code (hexadecimal, zero-padded), not a J1939 SPN. It matches the standard only where the signal itself is standard, and usually matches the title of this page by digit alone.
| FMI 4 | Connector or wiring harness defective (short circuit between VPSx and VMGx/vehicle ground or AU1), proportional solenoid valve(magnetic coil) defective, IT-ECU output defective, overvoltage peaks>36 volts at terminal 30 |
| SPN 1076 FMI 41076/4 · 1076.4 | voltage below normal or shorted to ground |
Safe to drive. Below — how much time you have and what happens if you keep going.
This is an electrical fault: an open, a short or a bad contact in the sensor circuit. The value it measures is most likely fine.
You can drive. But until the circuit is repaired this system runs blind and cannot warn you about a real failure.
Check the fuel filter and water trap, drain the water. In cold weather, suspect fuel waxing.
