My oil pressure gage is not getting a reading. I am sure there is pressure so i think it must be the sensor or "switch". Where is this on a 93 YJ? Is this easy to swap out? Thank you.
Oil pressure sending unit. Really easy to change out. I have a 2.5L '91 that this happened. The switch is right infront of the distributor on the engine block. One wire coming from it. Autozone should be able to look it up for you.
