Code P0118 Acura Description
The Engine Coolant Temperature (ECT) Sensor 1 is used for air/fuel ratio feedback control, ignition timing control, idle speed control, and other functions. ECT Sensor 1 resistance varies depending on the engine coolant temperature. As the engine coolant cools, ECT Sensor 1 resistance increases, and the Powertrain Control Module (PCM) detects a high signal voltage. As the engine coolant warms, ECT Sensor 1 resistance decreases, and the PCM detects a low signal voltage. If the ECT Sensor 1 output voltage is a set value, the PCM detects a malfunction and stores a Diagnostic Trouble Code (DTC).
