TROUBLESHOOTING

MULTIPOINT FUEL INJECTION (MPI)

13A-137

Inspection Procedure 8: The Engine Stalls when Starting the Car (pass out), The Engine Stalls when 
Decelerating

COMMENTS ON TROUBLE SYMPTOM

• The failure could possibly be caused by the mis-

fire due to the failed spark plug, improper air-fuel 
ratio at the accelerator pedal depression and so 
on when the engine stalls at the acceleration.

• The failure could possibly be caused by the 

improper air-fuel ratio due to the insufficient 
amount of intake air and so on when the engine 
stalls at the deceleration.

PROBABLE CAUSES

• Failed ignition system

• Failed intake air system

• Contamination around the throttle valve

• Improper compression pressure

• Failed engine-ECU

DIAGNOSIS PROCEDURE

NOTE: To protect the CVT, the CVT-ECU outputs,

throttle valve, retards the ignition or carries out fuel 
cut. At that time, the engine output seems to tempo-
rarily reduce, but there is no malfunction.
