My low oil pressure sensor keeps going off at random times i check oil and it is fine.no unusual engine sounds

The oil light comes on when the oil pressure sensor detects low oil pressure. The amount of oil has little to with it, although very low oil levels can cause loss of oil pressure. Since you aren't getting knocking, chances are the oil pressure sensor is defective. Replace it and monitor the situation closely. This could be a serious condition if allowed to escalated and it turns out to be an oil pressure issue.

Oil pressure sensor, or most likely, oil level sensor, either sensors, wires, or connections.

The light is likely fine. There is a sensor on the engine that senses the oil pressure. Either the sensor has gone bad, or you have low oil pressure.
Replacing the sensor isn't difficult, but if you have low oil pressure, that can cause the whole engine to go bad, and cost you a whole lot.

Take it to a mechanic and have them measure the oil pressure. If it's ok, they can replace the sensor and you'll be fine.

code p 0300 refers to random/multiple cylinder misfires detected ===causes spark plugs ---HT leads ---injector/s--ignition coil/s---low compression---wiring
code p 0522 refers to engine oil pressure sensor/switch--low voltage ===causes wiring short to ground ---engine oil pressure sensor /switch---ECM
for the first code having to alter the accelerator position ( which tells the ECM to let in more fuel indicates either a low pressure in the fuel manifold or that the injectors need cleaning
At high way speeds when the engine appears to be running good , it is still possible to have random misfires caused by low fuel pressures and /or dirty injector tips
It would be a good idea to check the oil pressure with a mechanical gauge ,then replace the oil pressure sensor/switch

suspect bad oil pump or clogged filter

LOW OIL PRESSURE WILL CAUSE OIL PRESSURE SWITCH OR SENDING UNIT TO DISABLE FUEL PUMP.CHECK FOR OIL PRESSURE.REMOVE OIL PRESSURE SENDING UNIT SCREW IN OIL PRESSURE GAUGE TESTER INTO BLOCK WHERE OIL PRESSURE SENDING UNIT GOES TURN ENGINE OVER CHECK FOR OIL PRESSURE SHOULD BE 18 PSI @ 2000 RPM. BESURE TO WRAP TEFLON PLUMBERS TAPE AROUND THREADS TO THE OIL GAUGE PRESSURE TESTER OIL WILL SPRAY EVERY WHERE.IF YOU ARE GETTING NO OIL PRESSURE.YOUR OIL PUMP FAULTY.YOUR ENGINE CRANKSHAFT BEARINGS WORN OUT.WORN DAMAGED CAMSHAFT OIL PUMP DRIVE GEAR OR OIL PUMP DRIVE ROD DAMAGED OR BROKEN. IF OIL PRESSURE OKAY OIL PRESSURE SENDING UNIT IS BAD.

The sensor is near the oil filter , you should remove it and fit a pressure gauge in it's place, start the engine and make sure the oil pressure is ok if so fit a new sensor.

If you just changed the oil, therefore we can assume that the oil level is correct at this time and that the correct oil viscosity (5W-20 or 5W-30) was used. Are there any unusual noises coming from the engine? Like, maybe "tapping" or "squeaking" sounds? If so, then the oil pump may have gone bad and is not supplying adequate oil pressure to the engine. Continued use of the vehicle can result in serious engine damage. Have the oil pressure checked by a shop ASAP.

If the vehicle is running normally and no unusual noises are heard, then the oil pressure sensor (a.k.a. oil pressure sending unit) may be sending a false signal to the dash "idiot light". Replace the oil pressure switch.

Hope this helps.

Have a Nice Day !!!

it is most definitely the oil pressure sender!

standing in front of your car, look behind your engine from above, below the head and screwed into the block on the right side is the sensor.

check if there is too much oil. over filling the engine with oil causes the oil to foam which leads to loss of oil pressure. it could also be the oil pressure sensor
