2. Look under the front of the car - if the engine oil sump is broken, if there is a leak from it.
3. Pay special attention to the oil filter. Oil may leak from under the rubber gasket of filter 1 if it is damaged or the filter is loose. If oil is leaking from under the oil filter, sometimes turning it clockwise a little is enough. Check the reliability of the contact of the wiring block on the oil level sensor 2 in the crankcase.
4. Check up reliability of fastening of a pad of wires on the gauge of an emergency drop in pressure of oil.
Warning! Be careful - hot engine parts can burn you, so work with gloves and long-sleeved clothing.
5. Remove the oil dipstick, wipe it with a clean cloth and reinsert. Remove the dipstick again and check the oil level. The level must be between the marks «MIN» and «MAX».
6. If the oil level is below the mark «MIN», add oil to normal, for this you can use a funnel from the neck of a plastic bottle. Start the engine.
If the signal lamp of insufficient oil level in the engine crankcase continues to burn on the indicator of the on-board control system, then the sensor itself is faulty or the fault must be sought in the electrical circuit of the sensor. When the engine oil level is normal, the low oil pressure warning light should go out and you can continue driving.
If the lamp is still on, check the oil pressure sensor. To do this, unscrew the standard oil pressure sensor and install a mechanical pressure gauge in its place. If the pressure at normal idle speed is more than 0.06 MPa (0.65 kgf/cm2) and increases with increasing speed, the sensor or its electrical circuit is faulty.
If, after eliminating all visible causes, the oil pressure in the engine is insufficient (oil pressure warning light on), requires diagnostics and engine repair (see section «Engine»).
Warning! Do not try to drive to the garage - the engine will fail. Have your vehicle towed for repair with the engine off.
