P0073 2017 Ford F150 Code - Ambient Air Temperature Sensor Circuit 'A' High
Quick Answer
The Ambient Air Temperature (AAT) Sensor is a thermistor device in which resistance changes with temperature. Common causes include Faulty Ambient Air Temperature (AAT) Sensor, Ambient Air Temperature Sensor harness is open or shorted, Ambient Air Temperature Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0073 2017 Ford F150 Description
Thermistor type sensors are considered passive sensors. A passive sensor is connected to a voltage divider network so that varying the resistance of the passive sensor causes a variation in total current flow. Voltage that is dropped across a fixed resistor in series with the sensor resistor determines the voltage signal at the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor.
The AAT sensor provides ambient air temperature information to the PCM for the temperature sensor correlation tests. The PCM also communicates the AAT sensor information to all other modules on the controller area network (CAN).
This Diagnostic Trouble Code (DTC) sets when the ambient air temperature (AAT) sensor signal is greater than the self-test maximum.
What are the Possible Causes of the DTC P0073 2017 Ford F150?
- Faulty Ambient Air Temperature (AAT) Sensor
- Ambient Air Temperature Sensor harness is open or shorted
- Ambient Air Temperature Sensor circuit poor electrical connection
