The same thing happend to my wife's car. DId you check the oil pan? They are know to rust out and crack, all the oil leaks out. My wife's car did the same thing and when I checked under the engine the oil pan was totally cracked and all the oil leaked in my driveway!

It could be either one. The oil pump is located inside the engine inside the oil pan and the oil pressure sensor is usually located on the side of the block somewhere near the oil filter.

Where the heck is the oil pressure sensor on a diesel rodeo

disregard auto advice as there is no connection
oil pressure sensor switches are located in the oil galley along the block or next to the oil filter housing
normally only one wire
I suspect that the wire to the switch is loose and not making proper contact
The fix here is to eliminate any mechanical problems ( pump and filter blockage ) by having an accredited service center remove the sender unit and fit a mechanical oil gauge to see what is happening with the pressure
If it reads within the specified limits, replace the sender unit or check the wire for loose , broken or shorting out

Flickering oil light

Oil light flickering on dash

Check/confirm the following (on 1987 models the wire harness in the engine bay is a known defect and the insulation is very prone to premature failure):
1) Oil level/condition/type of oil (15W40 is the general specified oil for these cars). To rule out low engine oil pressure have the system pressure checked by an accurate gauge installed in place of the oil pressure switch. The switch itself is screwed into the block, bottom left side if you are looking at the engine from under the hood (on the exhaust side). The sensor is indeed a switch - spring-loaded and normally closed (open when there is pressure).
2) The oil pressure switch wire is run around the front of the engine, secured by a sheath and clips. Check to ensure the insulation of the wire is intact and not chafing anywhere - trace it out carefully. It's a one-wire design, grounded by the threads of the sensor into the block. A good test is to disconnect the wire at the sensor and drive the car. If the light is still flickering, you have an intermittent short.
3) If the oil level is normal, its condition is good and of the correct weight, it is entirely possible that the oil pump strainer is clogged. This results in low oil pressure. The other possibility is that the oil pressure relief valve in the oil pump is sticking open. In either instance (provided they are true), the oil pump should be cleaned or replaced - something that is a formidable job as removal of the oil pan involves either pulling the engine or dropping out the subframe and related components. Do not use engine oil flush treatments - they tend to overload the oil filter and cause the oil pump pressure relief valve to open and could lead to serious engine damage.

These are the usual things I would check first before condemning the engine. Loss of power, rough running and metallic knocking/thumping sounds would point towards an engine rebuild, especially if they are all present at the same time. But if the engine is running well and quietly, the turbo spools and is also quiet, then start with the aforementioned electrical tests of the oil pressure sensor switch and go from there.

Oil light blinks on

If your oil level is good, that is between the low and high marks, that light blinking is an indicator there is a problem with your oil pressure. The light flashing could be low oil level, a bad oil pressure sensor, your oil pump going out or a clogged line or pick up. Start by checking your oil level, then test the sensor if both are good drain your oil and pull the oil pan off to see if the pick up is clogged, if it is clean it. If everything is good at this point then the problem is the pump itself and you'll need to replace the pump.

The oil light goes on and off even with a full engine of oil. Could this problem be from the oil pump or a loose belt?

check the wiring and connections to the oil sender[sensor-pressure switch]if good change oil and do a flush possible sludge build up -if still flickering have a pressure test on oil pump [possible oil pump going bad]

Oil light on when oil is full

a loose connection WILL NOT cause flickering oil light unless your your oil is empty at the same time a connector is loose. This flickering is most likely caused by clogged oil ports or failing oil pump. When this happens there is insufficient oil running through the engine, causing the sensor to activate the light intermittedly. Have this checked immediately to prevent extensive engine damage. Hopefully this helps!!

Oil light flickers on at idle and when stopping. Oil level is correct. Engine temp OK. Changed the oil to 10 w 40 but light still flickers.

before replacing the oil pump, try replacing the oil filter with one from mazda. there really is a difference in oil filters. if this doesnt cure the issue, youre going to need to replace the oil pump.

Oil pressure

Could be the oil pump going bad. The oil sensor registers oil pressure, not oil level. If it isn't pumping oil, the light will come on.

Oil light when idling

Have an oil pressure test done.
One of 4 things could possibly cause that.
Bad oil pressure sending unit.
just the oil sending unit.
weak oil pump.
low oil---check oil, see if it needs any.

Oil Pump light flickering + rough idle on 1996 Nissan Maxima

Sounds more like the Throttle Position Sensor or another sensor is letting the engine RPM's drop too low. When the RPM's are too low, the oil pump is not pumping enough oil.
