   Result	Proceed to
   DTC P0087-00 is output	A
   DTC P0087-00 and other DTCs are output	B

   HINT: 

   If any DTCs other than P0087-00 are output, troubleshoot those DTCs first.

Result: 

B 

GO TO DTC CHART. Refer to  DIAGNOSTIC TROUBLE CODE CHART [11/2018 - 10/2019]  , or refer to  DIAGNOSTIC TROUBLE CODE CHART [10/2019 - 08/2020] 

Result: 

A 

See step  3

1. In accordance with the display on the GTS, check the value of Freeze Frame Data item "Fuel Level" stored when the DTC was detected.

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

   Tester Display
   Fuel Remaining Volume

   Standard

   Freeze Frame Data Item	Standard
   Fuel Remaining Volume	15% or more

   HINT: 

   • DTC P0087-00 may be stored if the engine stopped after running out of fuel or the vehicle temporarily ran out of fuel when the amount of fuel was low.
   • If Freeze Frame Data item "Fuel Level" is not displayed, based on the interview with the customer, check if the low fuel level warning was not displayed when the MIL illuminated.

See step  4

1. Connect the Techstream to the DLC3.
2. Start the engine and warm it up until the engine coolant temperature reaches 75°C (167°F) or higher.
3. Turn the Techstream on.
4. Enter the following menus: Powertrain / Engine / Active Test / Control the Injection Mode / Data List / Coolant Temperature, Injection Mode and Misfire Count Cylinder #1 to Misfire Count Cylinder #4.

   Powertrain > Engine > Active Test 

   Active Test Display
   Control the Injection Mode

   Data List Display
   Coolant Temperature
   Injection Mode
   Misfire Count Cylinder #1
   Misfire Count Cylinder #2
   Misfire Count Cylinder #3
   Misfire Count Cylinder #4

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

   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

   HINT: 

   Perform "Inspection After Repair" after replacing the direct fuel injector assembly.

   Refer to INITIALIZATION [11/2018 - 10/2019] , or refer to INITIALIZATION [10/2019 - 08/2020]

Result: 

B 

REPLACE DIRECT FUEL INJECTOR ASSEMBLY. Refer to  REMOVAL [11/2018 - 08/2020] 

Result: 

A 

See step  5

1. Check the fuel pump operation (for low pressure side).

   Refer to PROCEDURE - Step 1

   HINT: 

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

   Refer to INITIALIZATION [11/2018 - 10/2019] , or refer to INITIALIZATION [10/2019 - 08/2020]

   Result

   Proceed to
   OK
   NG

Result: 

NG 

REPLACE FUEL PUMP (FOR LOW PRESSURE SIDE). Refer to  REMOVAL [11/2018 - 08/2020] 

Result: 

OK 

See step  6

1. Check the fuel pressure (for low pressure side).

   Refer to PROCEDURE - Step 2

   Result

   Proceed to
   OK
   NG

Result: 

NG 

REPAIR OR REPLACE FUEL SYSTEM 

Result: 

OK 

See step  7

1. Discharge the fuel pressure.

   HINT: 

   DTCs may be stored during this inspection. Check for DTCs and clear them using the GTS.

   1. Disconnect the fuel suction tube with pump and gauge assembly connector.
   2. Disconnect the fuel (engine room side) pump assembly (for high pressure side) connector.
   3. Start the engine.
   4. After the engine has stopped on its own, turn the ignition switch off.

      HINT: 

      If the engine does not stop naturally, perform direct injection by racing the engine to reduce the fuel pressure [Fuel Pressure (High)] and stop the engine.

   5. Crank the engine again and make sure that the engine does not start.
   6. Connect the fuel (engine room side) pump assembly (for high pressure side) connector.
   7. Connect the fuel suction tube with pump and gauge assembly connector.
2. Turn the ignition switch to ON.
3. According to the display on the GTS, read the Data List.

   Powertrain > Engine > Data List 

   Tester Display
   Fuel Pressure (High)

   HINT: 

   Use the snapshot function to record the value displayed or make a note of it.

4. Start the engine.
5. Read the change in the Data List item "Fuel Pressure (High)" after discharging the fuel system pressure and after starting the engine.

   Powertrain > Engine > Data List 

   Tester Display
   Fuel Pressure (High)

   OK

   The value of the Data List item "Fuel Pressure (High)" changes.

   Result

   Proceed to
   OK
   NG

Result: 

NG 

REPLACE FUEL PRESSURE SENSOR (FOR HIGH PRESSURE SIDE). Refer to  REMOVAL [11/2018 - 08/2020] 

Result: 

OK 

See step  8

1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Turn the Techstream on.
4. Clear the DTCs.

   Powertrain > Engine > Clear DTCs 

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