Found a sensor im guessing this afternoon when doing an oil change. Kinda tucked behind the bumper on the driver side. Any ideas what it is? It's got two yellow wires running to it. Is it some kind of temp sensor for like the ambient air? Thanks in advance for your help.

 

With your hood open, stand directly in front of your radiator and look down. You will see a tube with some loom over it and a bracket for a sensor. Do you see the sensor in the bracket or does it look like there's a missing piece there? If so, that sensor you found maybe your ambient temp sensor.
