2000 grand voyager oil warning alarm

The oil pressure light coming on at idle is not a big worry, so long as it goes out as soon as revs rise.. First step is to remove the oil pressure sender unit and screw in an oil pressure gauge. a mechanic can do this for you. This will tell you if the sender is faulty (common enough) or the oil pressure is low. A rule of thumb is to have about 10 psi per 1000 RPM in the normal rev range

If it is indeed low, possible causes are
- worn big end or main bearings (the car is old enough)
-faulty or weak over-pressure relief valve in oil pump
-worn or faulty oil pump
-blocked or sludged up oil passages
-blocked or sludged up oil pickup strainer mesh in sump

Some of these can be investigated by putting the car on a hoist and removing the sump

I would say your oil pump might be an issue. Your engine may also have clogged ports that the oil runs thru
Btw, you also have to consider the milage. Thst is enough for a pump to be an issue.

-Sound like every low oil.
-Did you check oil level..? Is it at the area indicated that " Full" ?
-If oil is full then possibly oil pump is worm out. So it doesn't supply oil to all moving parts.

Good luck

could also be wrong type of oil but worst case is the big end bearings inside the engine have gotten to big to maintain oil pressure and as you guessed the oil pump could be worn out, i would try changing oil pump first.

750 rpm?

your revs are too low.

The engine speed drives the oil pump via the timing belt.

too low revs = poor pump speed = low pressure.

I'll bet when you rev the idle speed faster, the warning goes off?

make sure are using a genuine dodge oil filter and correct grade of oil to check further you need to have the oil pressure checked using a master gauge a garage would do this for you if ok replace pressure switch if very low could be pump and bearing wear is the idle speed set too low i would check this

An RED OIL LIGHT on your dash, means a LOSS OF OIL PRESSURE. Has nothing to do with HOW MUCH OIL IS ON THE DIPSTICK. Now , does it just flash for a couple of seconds, or is it on steady ? Is there any engine noise ? Hope this helps

change your oil,it could be too thin,see if that fixes it

My friend that alarm is telling you u have low oil pressure, do you want to destroy the new engine?? Find out if the eng really has low oil pressure, it may just be a defective oil press sending unit causing the alarm, have the press checked with a mechanical guage or just replace the sender and see if that cures the issue, the alarm is part of the Body Control Module and can't be disconnected.
