Car: 2011 Cruze
Back story: My wife has been driving this car, and within the past week she's been noticing a burning smell when stopped. I was thinking it was probably an oil leak or something, but I drove it this morning and found otherwise. It doesn't really smell like burnt oil. It is a burning smell, but I don't know how to really explain it. I popped the hood when I finally stopped, and I noticed that this part (sensor) in the picture below was smoking and it is the smell that we've been smelling.
Does anyone know what this part is, or why it might possibly be burning/smoking? It's located on the front of the motor.
