on throttle position are compared with throttle
position based estimated airflow.
Enable Conditions
• Engine running
• Throttle Actuation Mode is not OFF
• MAP Sensor is not failed
• MAF Sensor is not failed
• IAT sensor is not failed
Case 1
• Speed-Density Airflow - ETC estimated airflow 〉 9 g/s
Thresh-
old
Case 2
• MAF reading - ETC estimated airflow 〉 7g/s
Diagnosis Time
• Contineous
(More than 3.9sec. Failure for every 15.6sec. Test)
MIL On Condition
• 1 Driving Cycle
• Air Leakage between TPS
and MAFS
• Faulty throttle body
• Faulty PCM

MONITOR DTC STATUS
EAB43615
1.
Check DTC Status
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
4)
Read "DTC Status" parameter.
DTC TROUBLESHOOTING PROCEDURES
FLA -597
SCMF16159L
5)
Is parameter displayed "Present fault"?
YES
▶ Go to "System 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.
SYSTEM INSPECTION
EFDBC19F
1.
Visual Inspection
1)
Check the air hose between MAFS and throttle body is torn or installation.
2)
Check deforamtion, crack or installation of throttle valve(body)
3)
Has a problem been found ?
YES
▶ Substitute with a known-good Air hose or throttle body and check for proper operation.
If the problem is corrected,replace air hose or throttle body and then go to "Verification of Vehicle Repair" pro-
cedure.
NO
▶ Substitute with a known-good PCM and check for proper operation. If the problem is corrected,replace PCM
and then go to "Verification of Vehicle Repair" procedure.
NOTE
There is a memory reset function on scantool that can erase optional parts automaticallydetected and memorized by
PCM.
Before or after testing PCM on the vehicle, use this function to reuse the PCM on the others
