MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE>

13A-15

NOTE: After the ECM has detected a malfunction, the Malfunction Indicator Lamp (SERVICE ENGINE 
SOON or Check Engine Lamp) illuminates when the engine is next turned on and the same malfunction is 
re-detected. However, for items marked with a "*1" in the DTC NO. column, the Malfunction Indicator Lamp 
(SERVICE ENGINE SOON or Check Engine Lamp) illuminates only on the first detection of the malfunction.
NOTE: The codes marked with a "*2" in the diagnosis code number column have the following two conditions 
for illuminating the Malfunction Indicator Lamp (SERVICE ENGINE SOON or Check Engine Lamp).

• In case that the misfire causing the damaged catalyst is detected, the Malfunction Indicator Lamp (SER-

VICE ENGINE SOON or Check Engine Lamp) is illuminated at the time.

• In case that the misfire deteriorating the exhaust gas is detected, the Malfunction Indicator Lamp (SER-

VICE ENGINE SOON or Check Engine Lamp) is illuminated when the same malfunction is redetected 
after the next engine start.

NOTE: After the Malfunction Indicator Lamp (SERVICE ENGINE SOON or Check Engine Lamp) illuminates, 
it will be switched off under the following conditions.

• When the ECM monitored the powertrain malfunction three times* and met set condition requirements, it 

detected no malfunction. *: In this case, "one time" indicates from engine start to next engine start.

• For misfiring or a fuel trim malfunction, when driving conditions (engine speed, engine coolant tempera-

ture, etc.) are similar to those when the malfunction was first recorded.
