EASY TO OPERATE
1. Disassemble the oil pressure sensor first, then screw on the oil pressure gauge
2. Start the vehicle to operate it at a specified speed, the reading in the pressure gauge is the oil pressure of lubrication system
DIAGNOSTIC RESULT
Please refer to equipment manufacturers operation instruction and compare to the manufacturers recommended readings, to check if the reading is out of the normal range. And check if the dashboard light works well or not.
Below the minimum oil pressure: blocking oil strainer or oil filter, broken pressure-limiting valve spring , poorly working oil pump, low oil viscosity
Above the maximum oil pressure: high oil viscosity, blocking lubrication oil channel, blocking oil filter core and by-pass valve is difficult to open.
