Why is the oil light coming on intermittently?

Engine has correct amount of oil in it. Can start it & drive a short distance then the light comes on. Turn it off, start again short distance later the light is back on.

You either have a bad oil pump, too much clearance in engine components or a bad oil sensor.

It may appear if there is a particular sensor fails.
Try reset the indication using the following technique.
Sometimes the problem could be solved.
Advantage is you could use this technique in the future too.

If you can get an OBD 2 scanner off eBay (US$ 6), you could be able to communicate with your car ECU (Electronic Control Unit) using the smart-phone app.

So that, there is a chance to CLEAR all the error indications.

After that, if problem still persists, it means the vehicle need full scan (you can't do this at home, probably seek a vehicle garage).

Low oil pressure, caused by several things among them oil pressure sensor, oil pump, and partly clogged oil passage

Hopefully you don't have a bad oil pump. Could be losing pressure when pump fails causing light to come on. Don't buy cheap oil filters.

"Warning Lights" on the dashboard of "1995 Nissan Maxima"


The warning lights coming on with the key in the on position is normal. If the key is turned to the start position and the engine will not crank over, suspect an internal starter motor problem or lack of power to the starter solenoid. You can try tapping on the starter motor with a blunt object while someone holds the key in the crank position to see if it starts when this problem occurs. If it starts using this procedure, the starter motor will be defective

3.5L V6. Why does oil pressure light turn on intermittently?


1. As a basic measure I would make sure the correct grade and spec oil is going in the engine. You can no longer trust that a local mechanic or even a dealer service center will necessarily use the required product as stipulated by the manufacturer. It is always better to buy and supply your own so you know the correct product is being used.

2. I would not assume there is a problem with the oil pressure warning light even though there could be.
The first thing the mechanic should have done when you reported the oil pressure issue is to hook up an independent mechanical oil pressure gauge and check oil pressure when the engine is hot at different RPMs. Any oil pressure issue will usually show up at idle when the engine has been warmed up properly and the engine oil is hot (unless you have some kind of intermittent oil pressure relief valve that is sticking). Just replacing parts without actually knowing what the oil pressures are at different RPMs is being sloppy and negligent.
This is what you need to do now. Contact a business that can hook up their own pressure gauge to your engine and have them check the oil pressure readings at various RPMs when the engine is fully warm. If there is a low oil pressure issue it will show up on the oil pressure gauge. As you have a new oil pump there should be no issue now with oil volume or a sticking oil pressure relief valve which on your engine should be part of the oil pump assembly.

3. Worn engines will not be able to sustain required oil pressures. Oil pressure is not produced by the oil pump. The oil pump produces oil flow but the resistance to flow is what produces the oil pressure and that resistance is created by fine clearances between operating engine parts especially on the crankshaft and components connected to it. Once the engine wears the clearances increase and the oil flows past the parts much more easily and produces/builds much less pressure.
How well your engine with over 90000 miles has been maintained depends on how often all the owners changed the engine oil and filter , whether they kept the engine oil level up to full (most owners rarely ever check oil levels between services) and whether they always used the correct product. Manufacturer oil change intervals shown in service schedules can be 10000, 12000 miles or more which is much too infrequent for the type of use 95% of private vehicles experience which typically are on the severe to very severe use end of the spectrum. Engine oil typically needs to be changed at least at half the mileage shown in service books (at least twice as frequently) and thus at least every 5000 miles if you want your engine to last.

Thanks for answering my Question so quickly. Can I still drive my car short distances like 30 km at a time?I'll have the camshaft checked asap.


If the oil light goes off while driving then short distances should be ok. BUT GET IT CHECKED ASAP! It may only need a bit of oil topped up to stop the light coming on

How can I fix my car with the oil light coming on. The engine does intermittent jerking during driving


Oil light usually indicates LOW oil pressure.. Which will kill your engi ne and cause very expense repairs. FIRST Check oil level, If the level is good. You need to find out if the engine really has low oil pressure. A new oil pressure switch is about $8.00 you might start there. If the light still comes on its a good posibilty your car has bad oil pres.. To find out for sure you will need to install a Pressure guage and check the actual pressure.. If the Oil Level is good and you still have low oil pressure The engine has internal wear or damage.. You should not drive it till you fix the low pressure problem. rebuild or replace engine. The intermittant "jerking" can be unrelated to the oil pres problem or you engine is going away because of the pressure problem.

Will make dodge trans temp light o d off


Run fault codes and look for a servo/sensor fault in the od section of the box. If the od band/clutch is slipping it will cause the oil to over heat. Have a pressure test done on the box to ensure proper operating pressure. Check for correct oil level in the gear box.

Oil light comes on, but there is enough oil in the car.


Either the oil pressure switch is bad (or its wiring are somehow shorting), or the oil pressure is low. For the later, it could be having an oil pump going bad or a clogged screen at its intake. I wouldn't drive the car until the problem is solved.
