Code P0118 2012 Nissan Rogue Description

The P0118 code on a 2012 Nissan Rogue indicates a problem with the engine coolant temperature sensor circuit being too high. The engine coolant temperature sensor is a crucial component that monitors the temperature of the engine coolant and sends this information to the engine control module (ECM). The ECM uses this data to adjust fuel delivery and ignition timing, ensuring optimal engine performance and efficiency. When the sensor circuit reads a temperature that is higher than expected, the ECM triggers the P0118 code.
