High Pressure Fuel Pump Inspection
NOTE:
- The following values are indicated by relative pressure from the fuel pressure sensor.
- Verify that the fuel pressure sensor is normal. (See FUEL PRESSURE SENSOR INSPECTION .)
- Connect the M-MDS to the DLC-2.
- Switch the ignition ON (engine off).
- Select the "FUEL_PRES", "LOAD" and "RPM" PIDs on the M-MDS. (See
ON-BOARD DIAGNOSTIC TEST [SKYACTIV-G 2.0, SKYACTIV-G 2.5]
.)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.
- Is the "FUEL_PRES" PID value 3.0 MPa {31 kgf/cm 2
, 435 psi}
or more while idling.
- If not as specified, replace the high pressure fuel pump. (See HIGH PRESSURE FUEL PUMP REMOVAL/INSTALLATION .)
