Code P0116 Chrysler Description

The P0116 Chrysler code indicates a problem with the engine coolant temperature sensor's performance. This sensor is responsible for monitoring the temperature of the engine coolant and sending this information to the engine control module (ECM). The ECM uses this data to adjust fuel mixture, ignition timing, and other engine functions to ensure optimal performance and efficiency. When this sensor fails or malfunctions, it can lead to inaccurate temperature readings, which may cause the engine to run too rich or too lean, leading to poor performance, decreased fuel efficiency, and potential engine damage.
