Malfunction Indicator Lamp: Testing and Inspection

The MIL (SERVICE ENGINE SOON telltale) will flash if a catalyst damaging misfire occurs with vehicle speed above 50 km/h (30 mph) and MAP greater than 70 kPa. Since the catalyst damaging misfire is a Type B DTC, the MIL will turn Off if the misfire terminates in that ignition cycle. However, if a catalyst damaging misfire occurs on the second consecutive trip and terminates in that ignition cycle, the MIL will again flash, but will be illuminated On steady as soon as the catalyst damaging misfire no longer exists. NOTE: Any non-catalyst damaging misfire is a Type B DTC.
