DTC P064A:00 (PCM, SKYACTIV-G 2.5T) DETECTION CONDITION AND POSSIBLE CAUSE

DTC P064A:00	Fuel pump control module error
DETECTION CONDITION	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. Diagnostic support note 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.
FAIL-SAFE FUNCTION	Not applicable
POSSIBLE CAUSE	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 unit terminal A-Fuel pump control module terminal 2C Fuel pump unit terminal B-Fuel pump control module terminal 2D 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 .) 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 .) (See DTC TABLE .) High fuel pressure sensor: P0087:00, P0089:00, P0192:00, P0193:00 High pressure fuel pump: P0091:00, P0092:00 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.
