Code P0118 2008 Nissan Rogue Description

The P0118 code for a 2008 Nissan Rogue indicates a problem with the Engine Coolant Temperature (ECT) Sensor Circuit being too high. The ECT sensor is responsible for monitoring the temperature of the engine coolant and sending this information to the engine control module (ECM). When the ECM detects that the ECT sensor reading is higher than normal, it triggers the P0118 code. This can lead to various issues with the vehicle's performance and overall operation.
