Title: A25A-FKS (ENGINE CONTROL): SFI SYSTEM (w/o Canister Pump Module): P008700; Fuel Rail / System Pressure - Too Low; 2019 - 2020 MY RAV4 [11/2018 - 08/2020]

DTC

P008700

Fuel Rail / System Pressure - Too Low

DESCRIPTION

The high-pressure direct injection fuel system consists of a spill control valve, check valve, fuel relief valve, fuel pressure sensor (for high pressure side), fuel pump assembly (for high pressure side) and direct fuel injector assemblies. The spill control valve adjusts the return volume of high-pressure fuel. The check valve mechanically opens and closes the path to the fuel delivery pipe. The relief valve releases the fuel back to the fuel tank if there is a malfunction in the high-pressure fuel system. The fuel pump assembly (for high pressure side) is installed to the cylinder head cover and operated by a cam installed to the end of the exhaust camshaft. Rotation of the camshaft moves the pump plunger inside the fuel pump assembly (for high pressure side) up and down, pressurizing the fuel. The pressurized fuel opens the check valve and is pumped into the fuel delivery pipe. The ECM controls the spill control valve to adjust the fuel pressure between 2.4 and 20 MPa (25 and 204 kgf/cm2, 348 and 2900 psi) and monitors signals from the fuel pressure sensor (for high pressure side) to maintain the target fuel pressure.

Fuel Rail / System Pressure - Too Low

Either of the following conditions is met (1 trip detection logic):

  • The actual fuel pressure is lower than the target fuel pressure value by 5 Mpa (51.0 kgf/cm2, 725 psi) or more for 10 seconds or more during in-cylinder injection.
  • The actual fuel pressure value is lower than the target fuel pressure value by 2 MPa (20.4 kgf/cm2, 290 psi) or more for 15 seconds or more during port injection only.
  • Leak of fuel
  • Fuel pipe (fuel tank - fuel pump assembly (for high pressure side))
  • Fuel pipe (fuel pump assembly (for high pressure side) - direct fuel injector assembly)
  • Direct fuel injector assembly
  • Fuel pump assembly (for high pressure side)
  • Fuel pump (for low pressure side)
  • Fuel pressure sensor (for high pressure side)

SAE Code: P0087

MONITOR DESCRIPTION

If the fuel pressure (for high pressure side) decreases despite an increase request signal being sent to the fuel pump assembly (for high pressure side) by the ECM, the ECM will illuminate the MIL and store this DTC.

CONFIRMATION DRIVING PATTERN

  1. Connect the Techstream to the DLC3.
  2. Turn the ignition switch to ON.
  3. Turn the Techstream on.
  4. Record the Freeze Frame Data.
  5. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  6. Turn the ignition switch off and wait for at least 30 seconds.
  7. Start the engine.
  8. Turn Techstream on.
  9. Based on the engine speed, engine load, injection mode and other conditions displayed in the Freeze Frame Data, reproduce the conditions present when the DTC was stored.
  10. Enter the following menus: Powertrain / Engine / Trouble Codes.
  11. Read the pending DTCs.

    HINT:

    • If a pending DTC is output, the system is malfunctioning.
    • If a pending DTC is not output, perform the following procedure.
  12. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
  13. Input the DTC: P008700.

    Techstream Display

    Description

    NORMAL
    • DTC judgment completed
    • System normal

    ABNORMAL
    • DTC judgment completed

    INCOMPLETE
    • DTC judgment not completed
    • Perform driving pattern after confirming DTC enabling conditions

    HINT:

    • If the judgment result is NORMAL, the system is normal.
    • If the judgment result is ABNORMAL, the system has a malfunction.

CAUTION / NOTICE / HINT

HINT:

Read Freeze Frame Data using the Techstream. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

PROCEDURE

1.

CHECK FUEL LEAK

(a) Check around and beneath the vehicle for fuel leaks, fumes, etc.

OK:

No fuel leaks present.

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(c) Turn the Techstream on.

(d) Enter the following menus: Powertrain / Engine / Trouble Codes.

(e) Read the DTCs.

Powertrain > Engine > Trouble Codes

Result

Proceed to

3.

CHECK SHORTAGE OF FUEL

(a) 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(P008700) > Freeze Frame Data

Tester Display

HINT:

  • DTC P008700 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.
