DTC DETECTING CONDITION AND TROUBLE AREA

DTC detecting condition	Trouble area
When running after engine warmed (2 driving cycle detection logic). Short term fuel trim less than -11 % or long term fuel trim less than -11% and total trim less than -30% is detected. Fuel trim too rich Output voltage of HO2S-1 is more than 0.45 V for specified time after output voltage changed into high condition from low condition (less than 0.4 V). (2 driving cycle detection logic)	Vacuum leaks (air inhaling) Exhaust gas leakage Fuel pressure out of specification Heated oxygen sensor malfunction HO2S-1 or its circuit MAF sensor poor performance ECT sensor poor performance Fuel level sensor.
