My oil pressure gauge on my dash usually changes with my throttle input. It recently stopped working either being at max pressure or 0 pressure. My temp is perfect, no abnormal sound, engine runs perfectly. I'm thinking its just the oil pressure sensor but I want to make sure driving it like this wont cause any damage such as if the computer isnt getting proper oil pressure readings and wont properly manage the pressure.

Hello,

I would check the oil level first if okay and the engine is not making any funny noises. I would replace the oil pressure sensor. Here is the location:

Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.

Cheers, Ken
