HINT: 

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

1. Disconnect the No. 2 fuel pressure sensor (for low pressure side) connector.
2. Turn the ignition switch to ON.
3. Measure the voltage according to the value(s) in the table below.

   Standard Voltage

   Tester Connection	Condition	Specified Condition
   D11-1 (VC) - D11-3 (E2)	Ignition switch ON	4.75 to 5.25 V
   D11-2 (PFL) - D11-3 (E2)	Ignition switch ON	4.4 to 5.6 V

4. Turn the ignition switch off and wait for at least 30 seconds.
5. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   D11-3 (E2) - Body ground	Ignition switch off	Below 1 Ω
   D11-1 (VC) - D11-2 (PFL)	Ignition switch off	171 to 189 kΩ

   HINT: 

   Perform "Inspection After Repair" after replacing the No. 2 fuel pressure sensor (for low pressure side).

   Refer to INITIALIZATION [12/2019 - 10/2021] , or refer to INITIALIZATION [10/2021 - ]
