Has 4 or 5 wires on it?

 

i dont think its the MAF cause thats is the sensor near the filter. this is the sensor near the turbo. its part of the fitting that the pcv line is attached to.

 

The one on the PCV line, where it joins the air hose to the turbocharger, is a heater. It prevents water vapor from the PCV system from freezing at the inlet to the turbocharger.
