Oil light flickered once in a while for two days. Check level---good.....light came on solid now..I suspect the pressure sending unit first..If I don't have pressure I would suspect the pump......How involved is getting to the pump........Been employed as Aircraft mechanic for about 25 years..................and aircraft can be quite complex without a good manual to follow

disregard auto advice as there is no connection
oil pressure sensor switches are located in the oil galley along the block or next to the oil filter housing
normally only one wire
I suspect that the wire to the switch is loose and not making proper contact
The fix here is to eliminate any mechanical problems ( pump and filter blockage ) by having an accredited service center remove the sender unit and fit a mechanical oil gauge to see what is happening with the pressure
If it reads within the specified limits, replace the sender unit or check the wire for loose , broken or shorting out
There may be a misunderstanding here. Yes the warning light comes on when the oil pressure drops below 5psi. If the light comes on and the switch is working correctly, the oil pressure is not good. Any problem with the pump or the screen would make the pressure not good. If the oil pressure has been checked with a mechanical gauge and it is above 20psi, the switch or the wiring could be faulty. You would need to have the pressure checked to know.
Of course it can be low of oil, but I assume you checked the oil level. It can be a bad oil pressure sending unit. Check the wiring at the oil pressure sensor and make sure it is connected tight and is not loose. If you see any oil leaking from the sensor replace it. If this started after an oil change remove the filter and install a Purolator, Wix, or Mazda filter. Then check the oil level after starting and running the engine for a couple of minutes. Top it off with the correct weight oil. If it is overfull of oil it can cause the pressure light to flicker. Make sure it is not overfull. If so, drain out any excess oil. Overfilling is just as bad as under filling. Also make sure you are using the correct weight oil which is more than likely 5w20. Check your owner's manual to be sure. I would suspect you will find the oil pressure sensor is the culprit.
Is your oil level good, did you check it again??
Your oil pump circulates oil through out the engine while it's running. If it fails, your destroy the engine. This may only take minutes. You should get an external oil pressure gauge hooked up to it to see if the oil pressure is good. Any good shop or garage should be able to do this.
see if you have any oil level or pressure sensors. sometimes these can get gunked up. You may need a new oil pump. I suggest you start using a senthetic oil (valvoline,mobil 1 is reccomended) after u get the problem fixed.
Yes there is a sensor located on the front of engine on the transmission side(single wire). It cannot be "reset". Possibly loose connection at the sensor,or a faulty sensor, OR... you could be losing oil pressure inside the engine somewhere(lets hope not) these engines are designed to run on very low oil pressure compared to cars of days gone by. The sonata 4 cylinder runs about only 12 psi. The V6 is 7.6 psi or more.
So if it is an oil pressure issue it is extremely important not to run the car before it is fixed or you will need an entire engine.
I think it is a connection problem more than an oil problem since you say it flickered. The oil guage is connected to the sensor at the engine. it is a small L shaped plug. Try finding the wire and tracing it back to the relay and fuse box.
Sounds like there is an oil pressure problem. Now this can be due to several factors. 1. low oil level in car
2. bad oil pump
3.bad oil pressure switch /sending unit
4. last but not least check oil filter and make sure its not clogged.
worn engine main/connecting rod bearings.
have pressure checked with a manual guage at oil pressure switch for the correct pressure. If that's good then the switch is bad and problem solved.
if it low then you will have to check pump and bearings. Contact if you need more help and thanks for using FIX YA
You are losing oil pressure! Don't run the engine without the proper repairs!! Check the oil level, if it's in the safe range, then it's possible that the oil pump is not working(this is a major deal, and could be a sign of other problems...if there's something plugging up the screen on the pickup tube, it could mean that something's coming apart inside the motor. I would drain the oil, and run it through a strainer to check for metal or plastic particles in the oil that could be from pistons, rings, timing gears... but dont' continue to run your engine without the proper oil pressure! the guage flickering means that it's dropping to unsafe pressure! a solid light means you've lost oil pressure.
... If there's no oil on the dipstick, add oil 1 quart.. and then recheck... add more as needed, but don't overfill. If t
