Code P0118 2010 Nissan Pathfinder Description

The P0118 code for a 2010 Nissan Pathfinder indicates a problem with the Engine Coolant Temperature (ECT) Sensor Circuit registering a high voltage. The ECT 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 injection, ignition timing, and other engine functions to ensure optimal performance and efficiency.
