P008800

Fuel Rail / System Pressure - Too High

Although the ECM is requesting the fuel pump assembly (for high pressure side) to open the spill control valve, fuel pressure increases 3 MPa (30.6 kgf/cm2, 435 psi) from target pressure for about 10 seconds (1 trip detection logic).

  • Fuel pump assembly (for high pressure side)
  • Fuel pressure sensor (for high pressure side)
  • ECM

DTC stored

  • SAE Code: P0088
  • DTC for Mexico Models: Applies

MONITOR DESCRIPTION

If the fuel pressure (for high pressure side) increases despite a decrease 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

HINT:

  • When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.

    Click here 2018 - 2024 MY Camry [03/2017 -        ]; A25A-FKS (ENGINE CONTROL): SFI SYSTEM: DTC CHECK / CLEAR

  • Permanent misfire and fuel system DTCs can only be cleared when performing the universal trip driving pattern when no malfunction is detected.
  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 the 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: P008800.
  14. Check the DTC judgment result.

    Techstream Display

    Description

    NORMAL

    • DTC judgment completed
    • System normal

    ABNORMAL

    • DTC judgment completed
    • System abnormal

    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 OTHER DTCS OUTPUT (IN ADDITION TO DTC P008800)

(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

DTC P008800 is output

A

DTC P008800 and other DTCs are output

B

HINT:

If any DTCs other than P008800 are output, troubleshoot those DTCs first.

2.

INSPECT FUEL PRESSURE SENSOR (FOR HIGH PRESSURE SIDE)

(a) Connect the Techstream to the DLC3.

(b) Start the engine.

(c) Turn the Techstream on.

(d) Enter the following menus: Powertrain / Engine / Data List / Fuel Pressure (High).

Powertrain > Engine > Data List

Tester Display

Fuel Pressure (High)

(e) According to the display on the Techstream, read the Data List while racing the engine.

OK:

Fuel pressure fluctuates.

HINT:

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