Inspection Procedure 9: The Engine Stalls when Starting the Car (Pass Out)
COMMENT ON TROUBLE SYMPTOM Engine stall on starting is possibly caused by misfire due to failed spark plug, improper air-fuel ratio at accelerator pedal depression or other faults.
PROBABLE CAUSE Failed ignition system Failed intake system Failed emission gas cleaning system Failed engine-A/T-ECU
| DIAGNOSIS PROCEDURE
| STEP 1. MUT-II/III diagnosis code Q: Diagnosis code set? YES: Inspection chart for diagnosis code (Refer to ). NO: Go to Step 2 .
| STEP 2. MUT-II/III data list Refer to Data list reference table . Item 14: Throttle position sensor (sub) Item 77: Accelerator pedal position sensor (sub) Item 78: Accelerator pedal position sensor (main) Item 79: Throttle position sensor (main) Q: Are the check results normal? YES: Go to Step 3 . NO: Perform the diagnosis code classified check procedure for the sensor that has shown an abnormal data value (Refer to Inspection Chart for Diagnosis Code ).
| STEP 3. Check EGR valve (stepper motor) itself. Check EGR valve (stepper motor) itself [Refer to GROUP 17 - Emission Control System - Exhaust Gas Recirculation (EGR) System - EGR Valve (Stepper Motor) Check <4G69> ]. Q: Is the check result normal? YES: Go to Step 4 . NO: Replace EGR valve (stepper motor).
| STEP 4. Check air intake from intake hose and inlet manifold. Q: Is the check result normal? YES: Go to Step 5 . NO: Repair.
