DTC P0116 - Engine Coolant Temperature Circuit Range / Performance Problem

CIRCUIT DESCRIPTION
A thermistor built into the engine coolant temperature sensor changes the resistance value according to the engine coolant temperature.
The structure of the sensor and connection to the ECM is the same as in the intake air temperature circuit malfunction (DTC P0100).






INSPECTION PROCEDURE

HINT: If diagnostic trouble codes "P0115" (engine coolant temperature circuit malfunction) and "P0116" (engine coolant temperature circuit range/performance) are output simultaneously, engine coolant temperature sensor circuit may be open.
Perform troubleshooting of diagnostic trouble code P0115 first.
