DTC P0116 Engine Coolant Temperature Circuit Range/Performance: DTC Detecting Condition

DTC DETECTION CONDITION REFERENCE CHART

Item		Detecting Condition & Fail Safe	Possible Cause
DTC Strategy		Coolant temp.not reached warm up state	Contact resistance in connectors Faulty ECT sensor
Enable Conditions	case 1	No ECTS failure 6 < Battery voltage < 16V
Enable Conditions	case 2	No relevant failure TOIL at engine stop of previous DC > 70°C(158°F) ECT at engine stop of previous DC > 70°C(158°F) Engine oil temperature at Start < 35°C(95°F) Intake Air Temperature at Start < 35°C(95°F)
Threshold Value	case 1	TCOmodel increase > Threshold But TCOmeas increase < Threshold(Threshold depends on Coolant start temp.)
Threshold Value	case 2	Start coolant temperature > 53°C(127°F) with oil temperature < 35°C(95°F)
Diagnostic Time	case 1	10~30 minutes
Diagnostic Time	case 2	Immediate
Fail Safe		Caculated engine coolant temperature is used for engine control Cooling / Condenser fan active with MAX speed EVAP. emission control function is controlled inminimum operation mode
Mil On Condition		2 Driving Cycles
