In general terms, the problem could be a faulty oil pressure switch, or you could actually have low oil pressure. You can verify which issue you have by checking oil pressure with a mechanical gauge or by replacing the switch.

SOURCE: 97 wrangler oil pressure drops when engine is at idle

check the engine oil level... you could possibly need to replace the oil pump soon... if you do not live in a cold climate i would consider using 30 or 50 weight oil. do NOT use that in a cold climate as the oil is like molasses when it gets cold.
that's only temporary. one other thing to consider is a clogged oil filter... when was the last time it was changed ?

SOURCE: 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.

SOURCE: engine high rev at stop and slowly goes to idle speed.

I've got Hyundai Lantra 1.6 year 2000. It's take time to start when it's hot. When I start my car it revs at about 2k-3k rpm. It also does it when I come to a stop. When I come to a stop it will stay at a higher rpm than that of idle speed. It drives ok when on freeway but uses more petrol. I have changed the water & petrol pump but no luck

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.

The oil light comes on at times and goes off as the rpms go up. What can be done about the light?

Maybe your engine is idling too slowly, If the revs are below say 700rpm the low pressure warning light could come on especially when the engine is hot.. If the idle speed is ok try a heavier grade of oil in the engine. Next try a new oil pressure sensor. It's got to be one of these things. Check the engine running temperature . An over-hot engine will cause the oil light to come on too.

Oil light in 1999 Toyota camry comes on when idling.

bad to worn out oil pump or excessive oil passage clearances that allowing more oil to pass thru them at a lower pressure due to the bigger opening. It can be a sign of an emminant engine failure due to oil starvation.

Oil pressure light comes on intermittently, often after getting up to normal operating temp. Goes off when engine revs. No knocking, runs fine, oil changed...still comes on. 160,000 miles.

try running a higher viscosity oil.
Instead of 5w30 (W stands for winter or cold viscosity) try a 10W30 or maybe more like a 20W50 the higher number is when the oil heats up.
You may try and add a can of No-Smoke or STP oil additive since you recently changed oil.

Oil pressure drops at idle

If there is no engine noise associated with this ow oil press reading then replace the oil pressure sending unit on the engine, it is defective, this is common on all cars.
