FUEL SYSTEM

▶

Go to "3.Signal Circuit Inspection (APS 2)" as follows.

NO

▶

Repair short in circuit and go to "Verification of Vehicle Repair".

3.

Signal Circuit Inspection (APS 2)

1)

IG KEY "OFF", ENGINE "OFF"

2)

Disconnect APS connector and ECM connector.

3)

IG KEY "ON"

4)

Check continuity between APS connector terminal 3 and chassis ground. (check short to ground )
Measure the voltage of terminal 3 of APS connector. ( check short to battery )

Specification : Check short to ground : Discontinuity ( Infinite

Ω

)

Check short to battery : 0.0V~0.1V

5)

Is APS 2 signal circuit insulated normally?

YES

▶

Go to "Ground Circuit Inspection".

NO

▶

Repair short in circuit and go to "Verification of Vehicle Repair".

GROUND CIRCUIT INSPECTION

E1384424

1.

Check ground circuit (APS1)

1)

IG KEY "OFF", ENGINE "OFF"

2)

Disconnect APS connector.

3)

IG KEY "ON"

4)

Measure the voltage of APS terminal 4. [ TEST "A" ]

5)

Measure the voltage of APS terminal 4 and terminal 5. [ TEST "B" ]
( terminal 4: Check + prove , terminal 5 : Check - prove )

Specification : [TEST "A"] Voltage - [TEST "B"] Voltage = below 200mV

6)

Is the measured voltage within the specification?

YES

▶

Go to "2. Check ground circuit (APS2)".

NO

▶

When "B" voltage is not detected : Repair open in ground circuit and go to "Verification of Vehicle Repair".

▶

When the voltage difference between "A" and "B" is above 200mV : Eliminate the causes of excessive resis-

tance and go to "Verification of Vehicle Repair".

2.

Check ground circuit (APS2)

1)

IG KEY "OFF", ENGINE "OFF"

2)

Disconnect APS connector.

3)

IG KEY "ON"

4)

Measure the voltage of APS terminal 1. [ TEST "A" ]

5)

Measure the voltage of APS terminal 1 and terminal 6. [ TEST "B" ]
( terminal 1 : Check + prove , terminal 6 : Check - prove )

Specification : [TEST "A"] Voltage - [TEST "B"] Voltage = below 200mV

6)

Is the measured voltage within the specification?

YES

▶

Go to "Component Inspection".

NO

▶

When "B" voltage is not detected : Repair open in ground circuit and go to "Verification of Vehicle Repair".

▶

VERIFICATION OF VEHICLE REPAIR

E7FDC3EA

After a repair, it is essential to verify that the fault is corrected.

1.

After connecting Scantool select "DIAGNOSTIC TROUBLE CODES(DTCs)" mode.

2.

Clear recorded DTC using Scantool.

3.

Drive the vehicle within DTC "Enable conditions" in "General information".

4.

After selecting "DIAGNOSTIC TROUBLE CODES(DTCs)" mode and check if DTC is recorded again.

5.

Are any DTCs recorded ?

YES

▶

Go to the DTC guide of recorded NO. in Scantool.

NO

▶

System operates within specification.
