The P0116 diagnostic trouble code (DTC) for a 2014 Toyota RAV4 indicates an Engine Coolant Temperature Circuit Range/Performance Problem. This code is triggered when the Engine Control Module (ECM) detects that the engine coolant temperature sensor signal is outside the normal operating range or is not performing as expected. The engine coolant temperature sensor is a crucial component that monitors the temperature of the engine coolant and provides this information to the ECM. This data is essential for the ECM to adjust fuel delivery, ignition timing, and other engine functions to ensure optimal performance and efficiency.
