1)

Connect scantool to Data Link Connector(DLC).

2)

IG "ON".

3)

Select "Diagnostic Trouble Codes(DTCs)" mode, and then Press F4(DTAL) to check DTC’s information from the
DTCs menu

SCMF16159L

5)

Is parameter displayed "Present fault"?

YES

▶ Go to "Terminal and connector inspection" procedure.

NO

▶ Fault is intermittent caused by poor contact in the sensor’s and/or PCM’s connector or was repaired and PCM
memory was not cleared. Thoroughly check connectors for looseness, poor connection, ending, corrosion, con-
tamination, deterioration, or damage. Repair or replace as necessary and go to "Verification of Vehicle Repair"
procedure.

TERMINAL AND CONNECTOR INSPECTION

EB412486

1.

Many malfunctions in the electrical system are caused by poor harness and terminals. Faults can also be caused by
interference from other electrical systems, and mechanical or chemical damage.

2.

Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or
damage.

3.

Has a problem been found?

YES

▶ Repair as necessary and go to "Verification of Vehicle Repair" procedure

NO

▶ Go to "Signal Circuit Inspection" procedure.

SIGNAL CIRCUIT INSPECTION

ECDD9E7E

1.

Check voltage

1)

IG "OFF" and disconnect CKPS connector.

2)

IG "ON" and ENG "OFF"

3)

Measure voltage between terminal 1 of CKPS harness connector and chassis ground.

FLA -368

FUEL SYSTEM

4)

Measure voltage between terminal 2 of CKPS harness connector and chassis ground.

Specification : Approx. 1.4V

5)

Is the measured voltage within specification?

YES

▶ Go to "Component Inspection" procedure.

NO

▶ Go to "Check open in harness" as follows.

2.

Check open in harness

1)

IG "OFF" and disconnect CKPS connector and PCM connector.

2)

Measure resistance between terminal 1 of CKPS harness connector and terminal C30-B (41) of PCM harness
connector.

3)

Measure resistance between terminal 2 of CKPS harness connector and terminal C30-B (21) of PCM harness
connector.

Specification : Below 1Ω

4)

Is the measured resistance within specification?

YES

▶ Go to "Component Inspection" procedure.

NO

▶ Repair open in harness, and go to "Verification of Vehicle Repair" procedure.

COMPONENT INSPECTION

E67111F8

1.

Check CKPS

1)

IG "OFF" and disconnect CKPS connector.

2)

Measure resistance between terminals 1 and 2 of CKPS connector.(Component side)

SPECIFIATION :

Resistance

825 ± 100Ω

3)

Is the measured resistance within specification?

YES

▶ Go to "Check signal waveform of CKPS" as follows.

NO

▶ Substitute with a known - good CKPS and check for proper operation. If the problem is corrected, replace
CKPS and go to "Verification of Vehicle Repair" procedure.

2.

Check signal waveform of CKPS

1)

IG "OFF" and connect scantool.

2)

ENG "ON" and Measure signal waveform at terminal 1 or 2 of CKPS.

REFERENCE SIGNAL WAVEFORM :

EGRF610K

3)

Is the measured siganl waveform normal?

YES

▶ Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deteriora-
tion, or damage. Repair or replace as necessary, and go to "Verification of Vehicle Repair" procedure.
