Hello,

That looks like your vehicle's Intake Air Temperature sensor (IAT). Your vehicle uses this sensor in conjunction with the Mass Airflow Sensor (MAF) to determine the volume and temperature of the air entering your engine and uses this to calculate the amount of fuel needed to make your engine run. Please get back to us with how everything turns out.

Thanks,
Alex

I thought is was the breathing tube.
How do I go by finding that part?
