DTC P107C: Fuel Rail Low Pressure Sensor (Low); DTC P107D: Fuel Rail Low Pressure Sensor (High) [11/2016 - ]: Procedure

1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG).
3. Turn the Techstream on.
4. Put the engine in inspection mode (maintenance mode).

   Tester Display
   Inspection Mode

5. Start the engine.
6. Enter the following menus: Powertrain / Engine and ECT / Data List / Low Fuel Pressure Sensor.

   Powertrain > Engine and ECT > Data List 

   Tester Display
   Low Fuel Pressure Sensor

7. Read the values.

   OK

   250 to 700 kPa (gauge) [36.263 to 101.535 psi (gauge)] (idling, warmed up engine).

   Result

   Low Fuel Pressure Sensor	Proceed to
   Approximately 720 kPa (gauge) [104 psi (gauge)] or higher	A
   Approximately 0 kPa (gauge) [0 psi (gauge)]
   (250 to 700 kPa (gauge) [36.263 to 101.535 psi (gauge)])*	B

   HINT: 

   *: The value must change when the engine is moving or stationary.

Result: 

B 

CHECK FOR INTERMITTENT PROBLEMS. Refer to  CHECK FOR INTERMITTENT PROBLEMS [11/2016 - ] 

Result: 

A 

See step  2

1. Disconnect the fuel pressure sensor (for low pressure side) connector.
2. Disconnect the ECM connector.
3. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   C72-1 (VC) - C1-126 (VCPF)	Always	Below 1 Ω
   C72-2 (PFL) - C1-125 (PFL)	Always	Below 1 Ω
   C72-3 (E2) - C1-93 (EPFL)	Always	Below 1 Ω
   C72-1 (VC) or C1-126 (VCPF) - Body ground and other terminals	Always	10 kΩ or higher
   C72-2 (PFL) or C1-125 (PFL) - Body ground and other terminals	Always	10 kΩ or higher

   Result

   Proceed to
   OK
   NG

Result: 

NG

1. Disconnect the fuel pressure sensor (for low pressure side) connector.
2. Turn the power switch on (IG).
3. Measure the voltage according to the value(s) in the table below.

   Standard Voltage

   Tester Connection	Condition	Specified Condition
   C72-1 (VC) - C72-3 (E2)	Power switch on (IG)	4.75 to 5.25 V

   Result

   Proceed to
   OK
   NG

   HINT: 

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

   Refer to INITIALIZATION [11/2016 - ]

Result: 

OK 

REPLACE FUEL DELIVERY PIPE WITH SENSOR ASSEMBLY (FUEL PRESSURE SENSOR (FOR LOW PRESSURE SIDE)). Refer to  REMOVAL [11/2016 - ] 

Result: 

NG 

REPLACE ECM. Refer to  REMOVAL [11/2016 - ]
