I also have a 98 Plymouth Grand Voyager, and I think I have the same problem. It started a couple of months ago, and although the 'ding ding ding' that goes with the oil light is very annoying, it usually goes away at highway speeds, and in recent very cold weather it has not happened as often. I talked to a mechanic last week, and he recommended that I try replacement of the oil pressure sending unit, which he said is located next to the oil filter. I told him that I have not done anything about it yet because I do not seem to have any performance problems. He said that if I really did have an oil pressure problem, the car would not be getting me to work and back every day. Apparently the oil pressure sending unit provides sensor input. Shortly after this problem started, I did have my oil system flushed/cleaned at a quick oil place. No impact on the 'ding ding ding' resulted. So I am thinking of having the oil pressure sending unit replaced. Have you done anything yet with your van?

My friend asked me to sell his 1998 Plymouth Grand voyager that has similar oil light problem. I went the Dodge dealer and the dealer wanted me to leave the car at their dealership for the inspection and will not tell me how to try the simple and quick methods to identify the problems. I then go to the auto store (like Auto Zone, etc..) to get a can of Oil flush to clean the engine gunk. I went home and pour one can of engine flush and turned on the engine for 5-10 min. while doing other tasks at home. When I came back after 10 min., the oil light disappeared. I turned off the engine and restarted it again. I then drove the car on the road to ensure that the oil light will not come on again. After one hour of test drive on the high way and local road, the oil light didn't come up again. I think that I had fixed it by adding more liquid (engine flush) into the engine. (P.S. Although that it is recommended that I change the whole engine oil after run the oil flush. And, I just have the oil change a week ago) After considering the factors of oil light issue, I beleive that the oil level is too low so the sensor triggered the oil light during the slower speed and the light went off when driving at 40-50 mile/hr. The higher speed will increase the oil pressure so the oil light will be off. However, the light will be on when your speed is low (low oil pressure) Therefore, I would recommend that you (1) flush the engine with some kind of engine flush to remove any gunk and then change the engine oil or (2) add litte more engine oil to see if you can fix your oil light problem. If not, then you may check if your engine gasket (rubber) is leaking. HCL

My oil light keeps comming on in my 98 Plymouth Grand Voyager 98.Whenever the car gets hot the oil light comes on. When I go-about 40 or 50 the light turns off. I spoke to a mechanic who informed me the problem was most likely gunk in the oil pan blocking the filter screen.He advised me to use 1qt of kerosene, run the engine until hot to clean gunk out of the oil pump and pan.I would the change the oil. I this good advice?

I also have a 1998 Grand Voyager with the same problem. What was really confusing was the problem started after I changed the front brake pads (same day). I'll try changing the switch today.

I have a similar problem - 98 grand voyager, 150K, although the light and alarm do not come on warm days 55+ degrees, but are constant below about 45 degrees. I have an oil leak and have been thinking that the leak has dripped into the sending unit and affected it. I have been driving it for several weeks like this and have have no performance issues.

Nostradamus wrote, �in the year 2004 there will be ding ding dings and oily lights�� This is very disturbing to me. Jk haha My Stratus started doing the same thing. I used to be a painter and so I had 5 gallons of xyolen (sp?) around and flushed my dodge work van with that. It worked, I guess. Allot of gunk came out. I then ran about 50 miles on cheap oil and changed it again to good oil, just to make sure all of the chemical was out.

Are you using the recomended oil? (ex.5W-30)This means it goes from 30 weight cold to 5 weight when hot or the other way . If it is coming on after you drive for a while you might want to try a lower weight oil.
