It is a well Known problem within the 2.7 L family ...
Here is the deal Go to the dealer get a Mopar oil sending unit.
once under the vehicle look to behind oil pan about center ways and take pigtail (wire) off sensor then remove unit .
once removed if alot of sludge is there clean area very good then install new unit and inspect wire if it connection even looks bad cut wire and add new wire (MAKE SURE TO USE HEAT SHRINK TAPE OR LIQIUD ELECTRICAL TAPE TO SEAL WIRE COMPLETELY. >>>>NOT JUST ELECTRIC TAPE<<<<)
Ok now thats done plug wire back into unit .
Note: 2.7 L engines also have sludge problems and need to have engine flush and oil pan dropped clean oil pump screen and pan then start useing synthetic oil you should be able to go about 10,000 miles useing synthetic and you will have to only change filter 2 or 3 times . this should solve issue and help extend life of motor.

While driving my chev 454 truck the oil pressure went to 0 psi


A leaking filter and oil pressure switch would cause the lack of oil pressure. Does the oil light work and does it go out now you have changed these parts. It only needs approx 8 psi to put the light out, the engine should run at approx 40 psi at 2000 rpm.

My oil light comes on at idle speed in my SantaFe 2006 CRDi engine


This is not necessarily a problem. If the oil is at correct level and viscosity grade, and the light always goes out with a small (not large) rise in revs, then it could possibly be OK. An engine does not need much oil pressure at idle, say 600-800 RPM.

It could also be a faulty sender unit on the engine, a worn oil pump, or a faulty oil pressure relief valve on the oil pump or in the filter.

To be sure, get an oil pressure gauge fitted to the sender outlet hole, and see what the reading is at various revs. If there is indeed a pressure problem by the gauge, try first a new oil filter. If not it is probably a faulty sender unit.

Have a reputable garage check the oil pressure with a manual oil pressure gauge. Very well may have worn internal parts, or weak oil pump. Thats the only way to know for sure.

Replace the oil pressure sending unit its giveing a false reading . The problem is when the engine is cold the oil pressure is low and it takes a little time to build up whem cranking the engine and that sends a signal to the computer PCM /VCM what ever but your 40 to 60 lbs oil pressure is graet its ideal .The unit switches when the oil pressure is high enough to trip the switch inside the sending unit and that is sent to the vehicle control module

Oil Pressure Light Comes On after 10 min of Driving


You may not have put the right amount of oil in your car, your oil pressure sensor could be faulty, or you may have a leak.

By revving your engine, you're increasing the pressure and thus turning off the light and making the sensor think that it's at the correct pressure.

Oil Pump light flickering + rough idle on 1996 Nissan Maxima


Sounds more like the Throttle Position Sensor or another sensor is letting the engine RPM's drop too low. When the RPM's are too low, the oil pump is not pumping enough oil.
