Code P0116 1997 Honda Civic Description

The P0116 diagnostic trouble code (DTC) for a 1997 Honda Civic indicates a problem with the Engine Coolant Temperature (ECT) Sensor 1 Circuit Range/Performance. 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 delivery and ignition timing to optimize engine performance and fuel efficiency. When the ECT sensor circuit is not operating within the expected range, it can lead to various issues with the vehicle's operation.
