Code P0073 2019 Ford F150 Description
The P0073 diagnostic trouble code (DTC) for a 2019 Ford F150 indicates a problem with the Ambient Air Temperature Sensor Circuit 'A' being too high. The Ambient Air Temperature Sensor is responsible for measuring the outside air temperature and providing this information to the vehicle's engine control module (ECM). This data is crucial for various functions such as fuel delivery, ignition timing, and emission control systems. When this sensor circuit reports a high voltage reading, it suggests that the outside air temperature is falsely being detected as excessively high.
