Does the oil light flicker only when the engine is 'idling'? Or does it flicker ALL the time? Does it flicker when the engine is cold? Or, only after the engine warms up? Cause could be low oil pressure (check oil level & condition- should be full and clean), could be the oil pressure sending unit going bad, could be electrical (short) in the oil pressure sending unit wire harness, could be sludge buildup in the crankcase clogging the oil pickup tube to the oil pump, or it could be a clogged oil filter or the oil pump is going bad. If you have an after-market oil filter installed, they somtimes rob the system of pressure. There is a Technical Service Bulletin on this for Hyundai Vehicles. You should use the genuine Hyundai Oil filter.
Does the Check Engine light come ON when this happens? Whenever the "Check Engine" light comes on, there is always a DTC (Diagnostic Trouble Code) stored in the ECM (Engine Control Module). You'll need an OBDII (On-Board-Diagnostics) scanner to retrieve any codes recorded/set in ECM. Once you do this and let us know what, if any codes are set, then we can go from there. OR, take/tow the vehicle into a Hyundai Service Center (dealership), pay the diagnostic fee. They will tell you EXACTLY what the problem is and what's needed to fix it (parts, labor, tax, time-frame, etc.). You could also go to http://www.hmaservice.com/ and register (vehicle by VIN). Afterward, you'll have access to technical information (manuals, wiring diagrams, service bulletins, etc) about your vehicle.

The flickering light usually indicates low oil pressure particularly at idle.Check oil quantity. How long since serviced and filter replaced. If these all good have your oil pressure tested with a master gauge. Some issues can be oil pickup slugged up or if high miler engine bearings.

Check the oil pressure with a mechanical test gauge and it will likely be ok, if so replace the oil pressure sending unit. Do not use any oil thickener in this engine it can damage the bearings.

Oil light on when oil is full


a loose connection WILL NOT cause flickering oil light unless your your oil is empty at the same time a connector is loose. This flickering is most likely caused by clogged oil ports or failing oil pump. When this happens there is insufficient oil running through the engine, causing the sensor to activate the light intermittedly. Have this checked immediately to prevent extensive engine damage. Hopefully this helps!!
