Methods and systems are provided for conducting an ambient air temperature (AAT) sensor test. In one example, a method may include adjusting a vehicle actuator to reduce a deviation of the AAT measured by an AAT sensor on board a vehicle from an expected AAT and remeasuring the AAT with the AAT sensor in response to the AAT measured by the AAT sensor deviating from the expected AAT by more than a threshold temperature difference. In this way, excessively inflated or depressed AAT measurements at the AAT sensor can be reduced, the accuracy and the reliability of the AAT sensor measurements can be increased, vehicle fuel consumption and emissions can be reduced, and vehicle drivability can be increased.
