3.0 250 2001 Warning horn beeps

[Aaronhl]

I have grounded the oil level sensor wires (telling the ECU the tank is full) But I am still getting 4 beeps every 2 minutes, even with the water separator wire disconnected - What can be the issue??

Seems like it could even be a malfunctioning MAP or Air sensor....

How many sensors feed into that warning system? I can't seem to find a good diagram on them.

Throttle sensor on the cable slide will cause beeps and will usually limit speed to 1800 r's. Disconnect and leave to test. Do you not connect the 2 wires from oil sender to stop beeps and test system? Not grounded? Been a while since I fixed mine.

The ecm reads ohms from the oil tank. Unhooking the wires or tying them together won't work. Take the pencil out of the tank and hold a magnet at the top, if the beeping stops, you need a new tank.

I looked in the tool box in my guide boat. I have a 4'' piece of 16 ga wire with solder at each end to make it easy to connect the oil sensor (harness side) connectors tabs together. I have used it before. Stops the oil beep, until you get it repaired.
