Land Rover found the normal value after replacing the intake wheel in Shen Xing.

Land Rover found the normal value of Shen Xing after replacing the intake wheel. The normal value of the absolute pressure of the intake manifold should swing around 0.3MPa. The detection method is as follows:

1, clamp the oil return hose. At this time, the reading of the oil pressure gauge is the maximum oil supply pressure of the oil pump, which should meet the technical requirements of the vehicle type, generally 2~3 times of the working oil pressure, that is, 0.0.75MPa.

2. Loosen the tubing clamp, restore the static oil pressure, remove the jumper of the oil pump relay, stop the operation of the oil pump, and wait for 5min. At this time, the reading of the oil pressure gauge is the maintenance pressure of the fuel supply system and should meet the technical requirements of the vehicle. The reading of the oil pressure gauge is generally the idle working pressure of the fuel supply system when the engine is idling, which is generally 0.25MPa or meets the technical requirements of the vehicle. When the idle working pressure is detected, unplug the vacuum tube on the fuel pressure regulator, and the oil pressure should rise to 0.3MPa.
