Code P0117 2007 Nissan Pathfinder Description

The P0117 diagnostic trouble code (DTC) for a 2007 Nissan Pathfinder indicates a problem with the engine coolant temperature circuit being too low. This code is set by the Engine Control Module (ECM) when it detects that the signal from the engine coolant temperature sensor is outside the expected range. The engine coolant temperature sensor is responsible for monitoring the temperature of the engine coolant and sending this information to the ECM. The ECM uses this data to adjust fuel delivery and ignition timing to optimize engine performance.
