Module is working. Something is wrong with the oil injection system. Either get a book and look into it, or have a shop look at it. Do not run it like that.

hope it helps

Constant beep is temp.
Beep beep beep is oil.
Disconnect blue wires. Still beeps not oil tank.
Disconnect tan wire to sensor. Still beeps not sensor.
Disconnect tan wire to control harness. Beep stops. Probably bad module again. Still beeps then you have short in wire harness probably.

Grounding the tan wire in from the wire harness sets off alarm.

A common problem with the tank is the float. The magnet is normally glued to the bottom of the float. It breaks loose and lays in the bottom telling the sensor the tank is empty. Unfortunately the fix is a new tank.
You can confirm this by taking the tank out and turning it upside down. The magnet will fall away from the sensor and the beep should stop.
