    Is the resistance between 0.3 - 1.1 ohms? 

    Yes No
    GO to  HP5. INSTALL a new Fuel Injection Pump.
    REFER to the fuel system WARNING information at the beginning of Pinpoint Test HC. GO to PINPOINT TEST HC .
    REFER to the appropriate Fuel Charging And Controls article .
    CLEAR the DTCs. REPEAT the self-test.
  5. HP5 CHECK THE FVR CIRCUIT FOR VOLTAGE 
    • Ignition ON, engine OFF.
    • Measure the voltage between:
      (+) Fuel Injection Pump Connector, Harness Side (-)
      FVR - Pin 2 Ground

    Is the voltage greater than 10 V? 

    Yes No
    GO to  HP7. GO to  HP6.
  6. HP6 CHECK THE FVR CIRCUIT FOR AN OPEN 
    • Ignition OFF.
    • PCM connector disconnected.
    • Measure the resistance between:
      (+) PCM Connector, Harness Side (-) Fuel Injection Pump Connector, Harness Side
      FVR - Pin E48, E65 FVR - Pin 2

    Is the resistance less than 5 ohms? 

    Yes No
    GO to  HP7. REPAIR the open circuit. CLEAR the DTCs. REPEAT the self-test.
  7. HP7 CHECK THE FVRR CIRCUIT FOR AN OPEN 
    • Measure the resistance between:
      (+) PCM Connector, Harness Side (-) Fuel Injection Pump Connector, Harness Side
      FVRRTN - Pin E30, E47 FVRRTN - Pin 1

    Is the resistance less than 5 ohms? 

    Yes No
    GO to  HP12. REPAIR the open circuit. CLEAR the DTCs. REPEAT the self-test.
  8. HP8 CHECK THE FVR AND FVRR CIRCUITS FOR A SHORT TO GROUND 
    • Measure the resistance between:
      (+) Fuel Injection Pump Connector, Harness Side (-)
      FVR - Pin 2 Ground
      FVRRTN - Pin 1 Ground

    Are the resistances greater than 10K ohms? 

    Yes No
    GO to  HP12. REPAIR the short circuit. CLEAR the DTCs. REPEAT the self-test.
  9. HP9 CHECK FOR THE FVR AND FVRR CIRCUITS SHORTED TOGETHER IN THE HARNESS 
    • Ignition OFF.
    • Fuel Injection Pump connector disconnected.
    • PCM connector disconnected.
    • Measure the resistance between:
      (+) Fuel Injection Pump Connector, Harness Side (-) Fuel Injection Pump Connector, Harness Side
      FVR - Pin 2 FVRRTN - Pin 1

    Is the resistance greater than 10K ohms? 

    Yes No
    GO to  HP10. REPAIR the short circuit. CLEAR the DTCs. REPEAT the self-test.
  10. HP10 CHECK THE FVRR CIRCUIT FOR A SHORT TO VOLTAGE 
    • Ignition OFF.
    • Fuel Injection Pump connector disconnected.
    • PCM connector disconnected.
    • Measure the voltage between:
      (+) Fuel Injection Pump Connector, Harness Side (-)
      FVRRTN - Pin 1 Ground
    • Ignition ON, engine OFF.

    Is any voltage present? 

    Yes No
    REPAIR the short circuit. CLEAR the DTCs. REPEAT the self-test. GO to  HP12.
  11. HP11 CHECK FOR CORRECT FUEL INJECTION PUMP OPERATION 
    • Fuel Injection Pump connector disconnected.
    • Visually inspect for:
      • pushed out pins
      • corrosion
    • Fuel Injection Pump connector connected.
    • Ignition ON, engine running.
    • Wait 15 seconds.
    • Carry out the PCM self-test.

    Are DTCs P0087 or P0088 present? 

    Yes No
    INSTALL a new Fuel Injection Pump.
    REFER to the fuel system WARNING information at the beginning of Pinpoint Test HC. GO to PINPOINT TEST HC .
    REFER to the appropriate Fuel Charging And Controls article .
    CLEAR the DTCs. REPEAT the self-test.    		 The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
  12. HP12 CHECK FOR CORRECT PCM OPERATION 
    • Disconnect all the PCM connectors.
    • Visually inspect for:
      • pushed out pins
      • corrosion
    • Connect all the PCM connectors and make sure they seat correctly.
    • Carry out the PCM self-test and verify the concern is still present.

    Is the concern still present? 

    Yes No
    INSTALL a new PCM. REFER to FLASH ELECTRICALLY ERASABLE PROGRAMMABLE READ ONLY MEMORY (EEPROM) , Programming the VID Block for a Replacement PCM. The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
