•  The difference between the actual fuel pressure and the target fuel pressure is 10 kPa {0.10 kgf/cm², 1.5 psi} or more even though the fuel pressure feedback amount on the low pressure side remains high.

•  This is a continuous monitor (other).

•  The check engine light does not illuminate.

•  FREEZE FRAME DATA is not available.

•  Snapshot data is available.

•  DTC is stored in the PCM memory.

•  Not applicable

•  Fuel pump unit connector or terminals malfunction

•  Fuel pump unit malfunction

•  Fuel pump control module connector or terminals malfunction

•  Short to ground in wiring harness between fuel pump unit terminal A and fuel pump control module terminal 2C

•  Open circuit in wiring harness between the following terminals:

•  Fuel pump control module malfunction

•  PCM connector or terminals malfunction

•  PCM malfunction

•  If only DTC P064A:00 is stored, a DTC inspection is not necessary because this is not a vehicle malfunction. In this case, clear DCT P064A:00 stored in the PCM. (See CLEARING DTC [PCM (SKYACTIV-G 2.5T)].)

Note

•  DTC P064A:00 may be stored again even if DTC P064A:00 has been cleared.

•  If DTC P064A:00 and any of the following DTCs are stored at the same time, repair the malfunctioning location according to the applicable DTC troubleshooting. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.5T)].)(See DTC TABLE [PCM (SKYACTIV-G 2.5T)].)

•  If there is any inquiry related to drivability by a customer, verify that DTCs other than DTC P064A:00 have been stored and repair the malfunctioning location according to the applicable DTC troubleshooting. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.5T)].)(See DTC TABLE [PCM (SKYACTIV-G 2.5T)].)
