SFI SYSTEM(for Rear Air Fuel Ratio Sensor), Diagnostic DTC:P02EE00, P02EF00, P02F000, P02F100

DTC Code	DTC Name
P02EE00	Cylinder 1 Injector Circuit Range/Performance
P02EF00	Cylinder 2 Injector Circuit Range/Performance
P02F000	Cylinder 3 Injector Circuit Range/Performance
P02F100	Cylinder 4 Injector Circuit Range/Performance

DESCRIPTION

Tech Tips

This DTC is applicable to w/ Canister Pump Module only.

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

Required Sensors/Components (Main)	Direct fuel injector assembly
Required Sensors/Components (Related)	ECM
Frequency of Operation	Once par driving cycle

CONFIRMATION DRIVING PATTERN

Connect the GTS to the DLC3.
Turn the engine switch on (IG).
Turn the GTS on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the engine switch off and wait for at least 30 seconds.
Turn the engine switch on (IG).
Turn the GTS on.
Start the engine and warm it up until the engine coolant temperature is 75°C [167°F] or higher [A].
Turn the engine switch off and wait for at least 30 seconds [B].
Start the engine and wait for at least 5 minutes [C].
Turn the GTS on.
Enter the following menus: Powertrain / Engine / Trouble Codes [D].
Read the pending DTCs.
Tech Tips
- If a pending DTC is output, the system is malfunctioning.
- If a pending DTC is not output, perform the following procedure.
Enter the following menus: Powertrain / Engine / Utility / All Readiness.
Input the DTC: P02EE00, P02EF00, P02F000 or P02F100.

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

Tech Tips

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.

CAUTION / NOTICE / HINT

Tech Tips

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

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

Connect the GTS to the DLC3.
Turn the engine switch on (IG).
Turn the GTS on.
Enter the following menus: Powertrain / Engine / Trouble Codes.

Read the DTCs.

Powertrain > Engine > Trouble Codes

Result

Result	Proceed to
DTC P02EE00, P02EF00, P02F000 and/or P02F100 is output	A
DTC P02EE00, P02EF00, P02F000 and/or P02F100 and other DTCs are output	B

Tech Tips

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

Turn the GTS on.
Enter the following menus: Powertrain / Engine / Trouble Codes.

Read the DTCs.

Powertrain > Engine > Trouble Codes

Result

Result	Proceed to
Only 1 DTC among DTC P02EE00, P02EF00, P02F000 and P02F100 is output	A

Tech Tips

The standard values shown are direct fuel injector assembly resistance values.
If the measured resistance value differs from the other cylinders and the injector resistance is normal, check the related cylinder as a poorly connected connector is suspected.
