Round shape oil pressure sender on the passanger side to the right of the oil filter. Oil pressure sender sends how much psi your oil pump pushes out to the ecu.
the oil sender unit need to be replace.
top up the oil or change the oil sender unit ???
Sounds like a wiring or sender unit problem. Ground wire at sender unit, see if it stays steady. If it still jumps around, wiring/gauge problem. If it stays steady, sender unit should be replaced. Good idea to do an oil pressure test as well.
Right behind the distributor.
Look at the top of the engine at the rear center
could be a couple things. the oil sender unit could be bad or you could just be a little low on oil.
no replace it before it blows out your oil will go with it.the sender is direct feed from the oil pump.
The oil pressure sending unit on a 5.9L V8 is on the top rear of the engine next to the distributor.
ON A 3.3 OR 3.5 THE SENDER SHOULD BE RIGHT BESIDE, OR IN CLOSE PROXIMITY TO, THE OIL FILTER.
