Code P0118 2019 Ford F150 Description

The P0118 code for a 2019 Ford F150 indicates a problem with the Engine Coolant Temperature Sensor 1 Circuit being too high. 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 delivery and ignition timing to ensure optimal engine performance and efficiency. When the sensor detects a high voltage signal, it triggers the P0118 code, indicating a potential issue with the sensor or its circuit.
