See step  3

1. Has the vehicle run out of fuel in the past?

   Result

   Proceed to
   YES
   NO

Result: 

YES 

DTC CAUSED BY RUNNING OUT OF FUEL 

Result: 

NO 

See step  4

Pre-procedure1

• Using the GTS, confirm the vehicle conditions recorded in the Freeze Frame Data which were present when the DTC was stored.

  HINT: 

  • Check the Freeze Frame Data sets recorded the moment the DTC was stored and after the DTC was stored.
  • Using the Freeze Frame Data, confirm the vehicle conditions when the DTC was stored, such as if the engine was idling with the shift state P, D or N or if the vehicle was being driven at a constant speed or accelerating.

  Powertrain > Engine > DTC(P0087-00) > Freeze Frame Data 

  Tester Display
  Target Fuel Pressure (Low) / Target Fuel Pressure 2
  Low Fuel Pressure Sensor

• Compare the difference in pressure between "Target Fuel Pressure (Low) / Target Fuel Pressure 2 and Low Fuel Pressure Sensor".

  Result

  Result	Proceed to
  Difference between Target Fuel Pressure (Low) / Target Fuel Pressure 2 and Low Fuel Pressure Sensor is within 200 kPa	A
  Difference between Target Fuel Pressure (Low) / Target Fuel Pressure 2 and Low Fuel Pressure Sensor is more than 200 kPa	B

Post-procedure1

• None.

Result: 

B 

GO TO FUEL PUMP CONTROL CIRCUIT. Refer to  Fuel Pump Control Circuit [10/2022 - 08/2023] 

Result: 

A 

See step  5

Pre-procedure1

• Put the engine in Inspection Mode (Maintenance Mode).

• Start the engine and warm it up until the engine coolant temperature reaches 75°C (167°F) or higher.

  Powertrain > Engine > Data List 

  Tester Display
  Coolant Temperature

• According to the display on the GTS, read the Data List with the Active Test "Control the Injection Mode" set to Direct.

  Powertrain > Engine > Active Test 

  Active Test Display
  Control the Injection Mode

  Data List Display
  Injection Mode
  Misfire Count Cylinder #1
  Misfire Count Cylinder #2

  Misfire Count Cylinder #4

  Result

  Injection Mode	Misfire Count	Proceed to
  Direct	There are no misfire counts	A
  	3 cylinders or more have misfire counts
  	1 or 2 cylinders have misfire counts	B

Post-procedure1

• None.

Result: 

B 

REPLACE DIRECT FUEL INJECTOR ASSEMBLY. Refer to  REMOVAL [10/2022 - 08/2023] 

Result: 

A 

See step  6

Pre-procedure1

• Put the engine in Inspection Mode (Maintenance Mode).

  Powertrain > Hybrid Control > Utility 

  Tester Display
  Inspection Mode

• Start the engine.

• Check that the fuel pressure fluctuates when the engine condition changes from idling to racing.

  Powertrain > Engine > Data List 

  Tester Display
  Fuel Pressure (High)

  Result

  Result	Proceed to
  Fuel pressure does not rise	A
  Fuel pressure does not fluctuate	B
  Fuel pressure fluctuates	C

Post-procedure1

• None.

Result: 

B 

REPLACE FUEL PRESSURE SENSOR (FOR HIGH PRESSURE SIDE). Refer to  REMOVAL [10/2022 - 08/2023] 

Result: 

C
