FUEL PRESSURE SENSOR INSPECTION [SKYACTIV-G 1.5, SKYACTIV-G 2.0]

id0140g8801300

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 ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 1.5, SKYACTIV-G 2.0)].) (See PCM INSPECTION [SKYACTIV-G 1.5, SKYACTIV-G 2.0].)

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 [SKYACTIV-G 1.5, SKYACTIV-G 2.0].)
•  If they match the standard, perform the voltage inspection. (See Voltage Inspection.)

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 ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 1.5, SKYACTIV-G 2.0)].) (See PCM INSPECTION [SKYACTIV-G 1.5, SKYACTIV-G 2.0].)

•  If not as specified, replace the fuel distributor. (See FUEL INJECTOR REMOVAL/INSTALLATION [SKYACTIV-G 1.5, SKYACTIV-G 2.0].)
