DTC P0116 Engine Coolant Temperature Sensor Circuit Range/Performance (4JJ3 with DPD)

1. DTC P0116 description

The engine coolant temperature sensor is installed near the thermostat housing. The engine coolant temperature sensor is a variable resistor and measures the temperature of the engine coolant. If the ECM detects that the difference of the engine coolant temperature is less than the calculated range under the predetermined conditions, the DTC is set. This DTC only runs once per ignition cycle within the effective conditions.

2. Condition for setting DTC P0116
