    This is a MALFUNCABLE OIL FAULT. It follows that you have low fuel pressure on the filter. The cause may be a clogged filter or a dragon. Valve in the head. Fuel pump . Leak in the system. Sensor itself malfunction. Ideally, about 3 bar should be on the free ones. The fault lights up if the power supply drops below 2 bar

    it remains to go to the computer and diagnose the error ...
    I bet that it may still be broken somewhere on the ankle, the link is tarnished from salt and mud, there is no full signal transition
