DTC P107A-15: Fuel Rail Pressure Sensor (Low) / Fuel Rail Pressure Sensor "B" Circuit Short to Battery or Open [12/2023 - ]: Procedure

HINT: 

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

Pre-procedure1

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

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

  Standard Voltage

  Tester Connection	Condition	Specified Condition	Result
  C70-1 (VC) - C70-3 (E2)	Ignition switch ON	4.75 to 5.25 V	V
  C70-2 (PFL) - C70-3 (E2)	Ignition switch ON	4.4 to 5.35 V	V

Pre-procedure2

• 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	Result
  C70-3 (E2) - Body ground	Always	Below 1 Ω	Ω
  C70-1 (VC) - C70-2 (PFL)	Ignition switch off	171 to 189 kΩ	kΩ
