MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS TSB Revision MULTIPORT FUEL INJECTION (MFI) 13A-13 NOTE: If the Malfunction Indicator Lamp (SERVICE ENGINE SOON or Check Engine Lamp) illuminates • 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 NOTE: After the Malfunction Indicator Lamp (SERVICE ENGINE SOON or Check Engine Lamp) illuminates, • 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. • The illuminated MIL for the vehicle identification number related faults is extinguished when the vehicle identification number is detected. NOTE: Sensor 1 of the heated oxygen sensor indicates the sensor mounted at a position closest to the P2128* 1 Accelerator pedal position sensor (sub) circuit high input P2135* 1 Throttle position sensor (main and sub) range/performance problem P2138* 1 Accelerator pedal position sensor (main and sub) range/performance problem P2195 Heated oxygen sensor (front) inactive P2228* 1 Barometric pressure circuit low input P2229* 1 Barometric pressure circuit high input P2252 Heated oxygen sensor offset circuit low voltage P2253 Heated oxygen sensor offset circuit high voltage U0101* 1 TC-SST-ECU time-out <TC-SST> U0121* 1 ASC-ECU time-out U0141* 1 ETACS-ECU time-out U1180* 1 Combination meter time-out DTC ITEM |
