Code P0116 Honda Description
The Powertrain Control Module (PCM) supplies voltage to the engine coolant temperature signal circuit (about 5 V) through a pull-up resistor. As the engine coolant cools, the Engine Coolant Temperature (ECT) Sensor 1 resistance increases and the PCM detects a high signal voltage. As the engine coolant warms, the ECT Sensor 1 resistance decreases, and the PCM detects a low signal voltage. If the ECT Sensor 1 output voltage does not reach a set temperature after starting the engine and driving at a set time, or when the difference between the ECT Sensor 1 output voltage while driving and the output voltage of ECT Sensor 1 after the engine has been stopped a certain length of time does not change a certain amount, the PCM detects a malfunction and stores a Diagnostic Trouble Code (DTC).
