SOURCE: Low Oil pressure light in idle at stop

Depending on the amount of miles, maintenance records, or how hard the car has been driven either by a previous owner, or by yourself. The engine's main crankshaft bearings or the connecting-rod bearings could be excessively worn.

Also, it could very well be a wiring problem to the sensor and/or computer causing the problem.

My 2007 Buick 3.9 liter oil light comes on and off. ..stays on for a while then goes back out. Checked the oil level all good. I did recently change the oil to GTX 5w30 extended milage oil. Any idea


The oil light comes on when the oil pressure sensor detects low oil pressure. The amount of oil has little to with it, although very low oil levels can cause loss of oil pressure. The best thing to do is to have the engine's oil pressure checked with a mechanical oil pressure gauge to ensure that the oil pressure is sufficient at all operating speed and temperatures. If the oil light is still flashing on and off and there is no indication of low oil pressure by the gauge, then replacement of the oil pressure sensor is recommended.

Oil warning light flashing mean?


Normally, if you get a oil warning light signal (flashing) could be a few things related to it. Number one, you are low on oil. Check your oil level and make sure it is at full level. Number two, is possibly oil filter is dirty, ( time for service,oil change) or problem with oil pump or oil pump pressure. BUT I would first start with checking oil level and then maybe a oil change.

The oil light remains on after an oil change/filter. The car is lexus 2000, Gs300. The milage is more than 100,125 miles. What is the prblem?


It depends. If you are talking about the RED oil pressure warning light, the problem is either that your engine has oil pressure problems or it has a defective oil pressure sending unit. If it is actual oil pressure problems, major engine repair or replacement will be necessary to fix it.

Oil pressure light is on and oil is on one of the


1st check quality oil and filter, if oil and filter is good, then remove engine oil pan , clean oil pump strainer, instal oil pan , add new oil and check.
if have oil on spark plug inside of cylinder, you need to overhaul the engine, if oil is over the spark plug ,change the valve cover gasket

OIL LIGHT GOES OUT AT 1000RPM OTHER WISE ITS ON 1 CHANGED OIL TWICE 2 RPL OIL SENDING UNIT 3 PERFORMED MOTOR FLUSH


I think you should have an accurate mechanical oil pressure test gauge installed in place of the oil sending unit and check to see what the actual oil pressure is. If it's 15 psi or so at an idle and about 35 psi or higher at 2500 rpm then your pressure is good and means you have some sort of issue between the sending unit and gauge. If the pressure is low, say below 10 or 5 psi at an idle with a warm engine and doesn't improve much at higher speeds then you actually do have low oil pressure, most likely due to worn bearings inside the engine. An accurate test gauge should tell the tale and help you figure out what is wrong. Hope this helps out a bit!

Low oil pressure light is on on 2000 lexus rx300. Doesn't need oil or an oil change. Not leaking oil.


try replacing the oil preasure switch, if that doesnt solve your problem then have your oil preasure tested, if it really doesnt have oil preasure it will cause internal engine damage so start with the switch and then go from there, hope this is helpful.

Oil pressure light at low RPM


Before you have major repair done on your car because of the "oil pressure light", review the list and see if any of these might be the source.  Some of the things on this list are things you can do yourself, some only done by a mechanic (inexpensively), and others require the aid of a mechanic.
1.  Check to see if you have a leak.  Low oil levels can make the oil sensor light come one.  Check your oil level following the manufacturers recommended procedure or use the information listed here http://autorepair.about.com/od/regularmaintenance/a/checkoil.htm.  If you do not have a low oil level, but still suspect a leak, place a drip pan under the oil plug overnight.  If you have a leak, you'll see signs of it there.  Then take the vehicle to a trustworthy mechanic and let them trace the leak.  It is possible for your engine to only leak when it is hot, so make sure you get the engine nice and warm before you put the car away for the evening and place the drip pan under your vehicle.  Other signs of an oil leak are listed below as well as an "oily" exhaust that leaves it mark on your bumper or "blue smoke" as you drive/idle.
2.  Check the coolant levels. If the coolant is low, the oil will heat up faster and cause a viscosity breakdown.  When the oil viscosity is low (= thin oil), the oil sensor light can come on.  If the coolant is low, add more.  Keep in mind that an engine running hot will heat the engine oil to the point that it thins out and burns off in the cylinders.  If the coolant level is fine, have the coolant (water) pump checked.  If the coolant is not circulating well through the engine, you'll probably have coolant boiling over, too.
3.  If you can afford to do it, change your oil to a higher or lower viscosity.  Refer to your maintenance manual and your trusted mechanic. I say this because, if your oil is thinning out too much because the viscosity is too low, your "check oil" light will come on.  If your engine oil is too thick, you engine will need added internal pressure to get it to circulate.  At lower RPM (just like thin oil), your engine oil light will come one.
4.  Have the oil pressure checked by other than an electronic means.  Your trusted mechanic can place an oil gage between your oil filter and the rest of the engine or on the oil fill cap of the engine.  If you are having an oil pressure problem that is seal-related, that should narrow it down.  If you can't afford to do that, when you get your next oil change, replace: the oil fill cap, PCV valve, and air filter.  All these contribute to the measurement of engine oil pressure by that picky little oil pressure sensor.
5.  Have the oil pressure sensor checked.  You may need some weird add-on to make it behave.  Do a search for the following part and read and you should have a better understanding: "part # 05017800AA a terminal/wire/vent to the oil pressure switch connector".  Never forget that sensor are usually engineered to report a problem well before a catastrophic failure can occur.
6.  If you're driving a high-milege car, make sure you are up to date on all of the engine-specific services.  For some vehicles, it is recommended that the head gaskets are replaced.  If you have internal engine leaks because of it, this will solve most of those issues.  Signs of this include: coolant visible in the crankshaft area (you can see this with the oil cap off), oil fouling your coolant (you can see this in the coolant reservoir), or smokey exhaust.  Expect your trusted mechanic to recommend that you change your spark plugs, timing belt, and cam shaft gasket at the same time.
7.  See if the oil pump needs to be replaced.  A faulty oil pump can contribute to low oil pressure as it fails (but hasn't failed, yet).  
8.  Do all of the above BEFORE you take to recommendation to have your engine replaced.
I have a 1998 Chrysler Cirrus (I know it's not a minivan, but hear me out).  I've been the single owner and have learned more about how engineering oversights or over-cautiousness can send you to the mechanic for just about everything.
Hope this helps!
