FUEL PRESSURE SENSOR INSPECTION [WITHOUT CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)]

id0140m1801300

Note
•  The fuel pressure sensor cannot be removed as a single unit. When replacing the fuel pressure sensor, replace it together with the fuel distributor as a single unit.

Function Inspection

1.  Connect the M-MDS to the DLC-2.

2.  Start the engine.

3.  Display the PID FUEL_PRES. (See OBD ON-BOARD SYSTEM READINESS TEST [PCM (WITHOUT CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5))].) (See PCM INSPECTION [WITHOUT CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)].)

4.  Compare the voltage and fuel value indications for the PID FUEL_PRES with the standard in the table indicated below.

•  If they do not match the standard, replace the PCM. (See PCM REMOVAL/INSTALLATION [WITHOUT CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)].)
•  If they match the standard, perform the voltage inspection. (See Voltage Inspection.)

Standard (without coolant control valve)

FUEL_PRES

V

MPa {kgf/cm2, psi}
Approx. 0.9
3.0 {31, 435}

Standard (with coolant control valve)

FUEL_PRES

Approx. 1.4
10 {102, 1450}


Voltage Inspection

1.  Connect the M-MDS to the DLC-2.

2.  Start the engine.

3.  Verify that the fuel pressure sensor output voltage (PID: FUEL_PRES) is within the specification. (See OBD ON-BOARD SYSTEM READINESS TEST [PCM (WITHOUT CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5))].) (See PCM INSPECTION [WITHOUT CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)].)

•  If not within the specification, replace the fuel distributor. (See FUEL INJECTOR REMOVAL/INSTALLATION [WITHOUT CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)].)
