Nov 15, 2018 · Maintenance inspection method (method): Check whether the oil pressure at the oil pressure sensor is greater than or equal to 0.7 bar. If there is no pressure gauge, remove the turbocharger (Thesupercharger) on the oil pipe to see if there is oil spray. Look at the oil dipstick and the position of the oil. See if the oil filter is blocked.

If there is no resistance, there will be no pressure; and pressure will never be higher than they load. In short, the pump is responsible for the rate of flow while the system it is attached to sets the pressure.
