What are the solutions for low engine oil pressure?

[SanMalia]

Engine oil pressure is too low processing method is: 1, unscrew the oil dipstick, see whether the oil pan oil is enough, whether the oil is too thin; 2, see whether the oil pressure gauge and sensor failure, remove the sensor wire directly grounded, if the oil pressure returns to normal or oil from the oil passage spray, the pressure is very sufficient, fingers can not hold the sensor is damaged, etc.; 3, use a good oil pressure gauge to replace the test, if the oil pressure is normal, the original oil pressure gauge is damaged; 4, check whether the oil pipe is broken, whether the pressure limiting valve is stuck, whether the oil filter is blocked; 5, check whether the oil pump is seriously worn.
