The following vacuum values are indicated by relative pressure from the fuel pressure sensor.
1. Verify that the fuel pressure sensor is normal..
2. Connect the M-MDS to the DLC-2.
3. Switch the ignition ON (engine off).
4. Select the “FUEL_PRES”, “LOAD” and “RPM” PIDs on the M-MDS..
CAUTION:
-
If the engine is run at a high speed, it could be damaged. When racing the engine, be careful not to increase the engine speed suddenly.
5. After the “LOAD” PID is 60% or more
