Toyota Corolla Cross: Cylinder 1 Injector Circuit Range/Performance (P02EE00,P02EF00,P02F000,P02F100)

DESCRIPTION

By using Partial Lift Fuel Injection Control to spray fuel before the needle inside each direct fuel injector assembly has fully opened, the injection of fuel by the direct fuel injector assembly can be precisely controlled at partial lift. Due to the influence on the injected fuel volume due to wear and variations between injectors, feedback control is implemented for partial lift fuel injection.

MONITOR DESCRIPTION

The ECM calculates the partial lift control learning value for each cylinder. The ECM counts the number of times that the partial lift control learned value exceeds the threshold, and if the total number exceeds the threshold, the ECM determines that partial lift control is malfunctioning and illuminates the MIL and stores a DTC.

MONITOR STRATEGY

Related DTCs	P02EE: Injection volume learning (Partial Lift [PL] learning) value reaches upper or lower limit (No. 1 cylinder) P02EF: Injection volume learning (Partial Lift [PL] Learning) value reaches upper or lower limit (No. 2 cylinder) P02F0: Injection volume learning (Partial Lift [PL] learning) value reaches upper or lower limit (No. 3 cylinder) P02F1: Injection volume learning (Partial Lift [PL] learning) value reaches upper or lower limit (No. 4 cylinder)

CONFIRMATION DRIVING PATTERN

HINT:

• After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

  Click here

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

  Click here

1. Connect the GTS to the DLC3.
2. Turn the ignition switch to ON.
3. Turn the GTS on.
4. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
5. Turn the ignition switch off and wait for at least 30 seconds.
6. Turn the ignition switch to ON.
7. Turn the GTS on.
8. Start the engine and warm it up until the engine coolant temperature is 75°C [167°F] or higher [A].
9. Turn the ignition switch off and wait for at least 30 seconds [B].
10. Start the engine and wait for at least 5 minutes [C].
11. Turn the GTS on.
12. Enter the following menus: Powertrain / Engine / Trouble Codes [D].
13. 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.
14. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
15. Input the DTC: P02EE00, P02EF00, P02F000 or P02F100.
16. Check the DTC judgment result.

    GTS 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 is malfunctioning.
    • If the judgment result is INCOMPLETE, perform steps [A] through [D] again.
    • [A] to [D]: Normal judgment procedure.

      The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.

    • When clearing the permanent DTCs, do not disconnect the cable from the auxiliary battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.

CAUTION / NOTICE / HINT

HINT:

Read Freeze Frame Data using the GTS. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can be helpful in determining whether the vehicle was moving or stationary, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.

PROCEDURE

1.	CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P02EE00, P02EF00, P02F000 AND/OR P02F100)

(a) Read the DTCs.

DTC P02EE00, P02EF00, P02F000 and/or P02F100 and other DTCs are output	B

HINT:

If any DTCs other than P02EE00, P02EF00, P02F000 and/or P02F100 are output, troubleshoot those DTCs first.
