HINT:

Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.

Disconnect the fuel pressure sensor (for low pressure side) connector.
Turn the ignition switch to ON.

Measure the voltage according to the value(s) in the table below.

Standard Voltage

Tester Connection	Condition	Specified Condition
E5-1 (VC) - E5-3 (E2)	Ignition switch ON	4.75 to 5.25 V
E5-2 (PFL) - E5-3 (E2)	Ignition switch ON	4.4 to 5.35 V

Turn the ignition switch off and wait for at least 30 seconds.

Measure the resistance according to the value(s) in the table below.

Standard Resistance

Tester Connection	Condition	Specified Condition
E5-3 (E2) - Body ground	Ignition switch off	Below 1 Ω
E5-1 (VC) - E5-2 (PFL)	Ignition switch off	171 to 189 kΩ

HINT:

Perform "Inspection After Repair" after replacing the fuel pressure sensor (for low pressure side).

Refer to INITIALIZATION [08/2020 - 12/2021] , or refer to INITIALIZATION [12/2021 - ]

Result

Proceed to
OK
NG

Result:

REPLACE FUEL PRESSURE SENSOR (FOR LOW PRESSURE SIDE). Refer to REMOVAL [08/2020 - 12/2021] , or refer to REMOVAL [12/2021 - 10/2022] , or refer to REMOVAL [10/2022 - 10/2023] , or refer to REMOVAL [10/2023 - ]

Result:

See step 2

CHECK HARNESS AND CONNECTOR (FUEL PRESSURE SENSOR (FOR LOW PRESSURE SIDE) - ECM)

Disconnect the fuel pressure sensor (for low pressure side) connector.
Disconnect the ECM connector.

Measure the resistance according to the value(s) in the table below.

Standard Resistance

Tester Connection	Condition	Specified Condition
E5-3 (E2) - C40-61 (EPFL)	Always	Below 1 Ω
E5-2 (PFL) - C40-107 (PFL)	Always	Below 1 Ω
E5-2 (PFL) or C40-107 (PFL) - Other terminals	Always	10 kΩ or higher

Result

Proceed to
OK
NG

Result:

REPLACE ECM. Refer to REMOVAL [08/2020 - 10/2022] , or refer to REMOVAL [10/2022 - 10/2023] , or refer to REMOVAL [10/2023 - ]

Result:

REPAIR OR REPLACE HARNESS OR CONNECTOR
