Note. The following vacuum values are given as pressure relative to the value of the fuel pressure sensor.
1. Make sure the fuel pressure sensor is good.
2. Connect the M-MDS device to the DLC-2 diagnostic socket.
3. Turn on the ignition (do not start the engine).
4. Select "FUEL_PRES", "LOAD" And "RPM" in the M-MDS instrument.
Attention. If the engine is running at too high a speed, it may be damaged. When accelerating the engine, be careful not to increase the engine speed excessively.
5. Pressing the accelerator pedal all the way, wait until "LOAD" on the instrument will show more than 60% and make sure that "FUEL_PRES" is approximately 15.0 MPa (153 kg/cm2). If the value obtained is not correct, replace the high pressure fuel pump with a new one.
