start your car, turn the wheels all the way to the left, now get on your hands and knees and look from behind the pass side front tire. look just past the oil filter over the axle is a sensor with a green plug, ( the one in the pic) if the plug is wet or dripping or pouring out its the sensor leaking.
ive blown like 3 of them out, took the last one into the hardware store, found a nut that fit the old one, then found a brass plug the same thread size, wrap the threads up with Teflon tape and put it in till its snug, then stop. or the housing will crack.
or, buy a oil pressure gauge and in stall it in the hole.
having it unplugged does nothing, no lights will come on from it. mines off for like 3 years now.
