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

DTC DETECTING CONDITION AND POSSIBLE CAUSE

Item		Detecting Condition & Fail Safe	Possible Cause
DTC Strategy	case 1)	Signal stuck Low	Contact resistance in connectors Defective cooling system Defective thermostat
DTC Strategy	case 2)	Signal stuck High
Enable Conditions	case 1)	No relevant failure 6 < Battery voltage < 16V
Enable Conditions	case 2)	No relevant failure Engine oil temp. at engine stop of previous DC > 70°C (158°F) Coolant temp. at engine stop of previous driving cycle > 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)	Coolant temperature signal variation since engine start < 2°C (4°F) when coolant temp. below 40°C (104°F) at start
Threshold Value	case 2)	Engine coolant temperature at start > 53°C (127°F)
Diagnostic Time	case 1)	10-30 minutes depends on coolant temp. at start
Diagnostic Time	case 2)	Immediate
MIL On Condition		2 Driving Cycles
