Hello, my name is***** will assist you.

The fault is for sea pump pressure. You could have a clogged strainer, some of the corrosion that you had inside the water intake could have broken off and is now blocking the sensor. A failed sensor, or a broken wire. start the gen and watch the exhaust water flow, if it is ok, but the code is still active, try the battery disconnect to reset the code after stopping the gen.
