Did you check the screen in the oil pressure passage, known problem with them, you can search it on you tube.

Yes we did it was clear

Ok I would install a manual oil gauge just to make sure the oil pressure is actually low, if it is then you need to replace the oil pump, if not then find the failure in the electrical system that is giving the wrong signal.

Yeah the oil pump is the next thing I will try we hooked the manual gauge up to it. It's reading low
