U are on the correct rack suspecting a clogged oil screen or a pump that is below average at low engine speeds.

SOURCE: 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!

SOURCE: oil light is on

I had the same issue on my '01. I hoped the issue would just go away, but when it didn't I took it into the dealership. They found a sensor that had gone bad and replaced it. Fortunately, it was not engine-threatening. As I understand it, oil lights are not designed to tell you if your oil is low, it usually means your pressure is low, which could mean a compression issue. Better get it checked out soon if you haven't already. You may want to find a good auto repair shop (I found one on cartalk.com) rather than taking to the dealer.

Most likely the oil pressure switch may be damaged. This is a simple procedure. Change and observe the results

SOURCE: need to replace oil pressure sensor/or sending

In my experience with neon's the sending unit is most likely not the problem. I feel that you will find that the oil pressure is actually low and that the oil pump is going out. If you change the sending unit and it doesn't change then you will know for sure. The sending unit is located on the side of the block near the oil filter. It has one wire and simply unscrews and the new one screws back in and re-attach the wire. Hope this helps. Good luck.

SOURCE: Oil light comes on below 1000 rpm's 1998 dodge stratus

If there is really a problem, resetting the computer won't fix it...if there is not a problem, you can reset and the light will stay off. After reset, you may have to drive the car a couple of hours before the light would come back on, because the computer...for lack of a better term..."re-learns" before giving proper readings. If your oil pressure is actually dropping, and it is not a computer glitch or a sending unit problem, then you likely have a problem with your oil pump. Good Luck! I hope you find this to be very helpful!

Oil light comes on when stopped at a light. Okay when moving. Oil levels are okay. Reving the engine when stops makes it go out.


Its possible the pressure light is faulty, or you really do have low oil pressure. The pressure is higher when the oil is cold than when the engine is warmed up.
You could replace the switch and see what happens, or get the pressure checked with a mechanical gauge in place of the switch.

I have a 2003 dodge neon and everytime I stop at a red light my oil light comes on but as soon as I take off it goes off. Oil has changed a month ago, it's full and still clean. What could cause t


Your motor is getting Tired or your Oil Pump is going bad.

Dodge has a problem with their motors and their Oil Passages get GUNKED really bad. This is what you should do,...

A. Get 1.5 Quarts of Diesel Fuel and drive to where you have your Oil changed

B. Add the Diesel Fuel to the Oil and let it IDLE (don't Drive the car under operating conditions). Let it Idle for 15-20 minutes and then have your Oil Changed

C. Have them use 20W-50 Oil, this is going to raise your oil Pressure and the light will not come on anymore.

Reason... Metal parts are wearing and that is oil gets into the system to lube the bearings. Pump Screen may be clogged and this will dissolve the Carbon Build up.

Good :Luck

2003 Dodge Neon Check Oil light wont go off. Car has oil-full, and just put in new Sensor.


Do you mean the oil level sensor was replaced, or do you mean the oil pressure sending unit was replaced?
If it was the oil pressure sensor was replaced, then I would look into an oil pump going bad, not supplying enough pressure to the oil pressure sensor. This can be tested by putting an oil pressure gauge into where the oil pressure sensor normally goes, bypassing the circuitry that leads to the dash light for the oil pressure.

If it was the oil level sensor, then check for bad wiring.

The oil light in my 2003 Neon keeps coming on.


it is most definitely the oil pressure sender!

standing in front of your car, look behind your engine from above, below the head and screwed into the block on the right side is the sensor.

My low pressure oil light keeps coming on when i stop and i just got my oil changed. The oil is not low. What could be the problem?


Hi,
That means LOW PRESSURE , not low in volume. Pressure is measured in PSI. The reason that your light comes on when you are at a stop is because your engine goes to idle at a stop and would normally have lower pressure. That doesn't mean you should get a low pressure light though.. I would have it checked by a pro right away as this could be your first warning before a serious problem.

Oil pressure light on at idle


Don't delay on this. Take the vehicle in and have the oil pressure sensor checked. It could be just the sensor or it could be something more serious. A drop in oil pressure could lead to catastrophic engine failure.
