Engine oil pressure can be measured using a dedicated oil pressure gauge or a regular oil pressure gauge (with a range of approximately 1 MPa) with the appropriate high-pressure hose and connector. The detailed procedure is as follows:
1. Disconnect the oil pressure sensor's wiring harness connector and remove the oil pressure sensor;
2. Screw the oil pressure gauge's hose connector into the screw hole where the oil pressure sensor is installed and tighten the connector;
3. Place the oil pressure gauge in a location where it will not come into contact with rotating engine parts or high-temperature components;
4. After starting the engine, check for oil leaks at the oil pressure gauge connector. If leaks are found, turn off the engine and retighten the connector;
5. Run the engine until it reaches normal operating temperature, and check the oil pressure gauge readings at idle speed and at the minimum 2000 rpm, comparing them with the standard pressure value.
