Sensor under right exhaust manifold on 3.6 V6?

[Pat Reddington]

My serpentine belt broke and severed the wiring near the front right side of the engine going back to a sensor under the exhaust manifold on the right side of the engine block.  

Can anyone assist tell me what this sensor is and help out with the wiring details?  I see three conductors from a broken wire and a four conductor plug going back to the sensor. The wire appears to come from the left side of the engine compartment wiring harness.  The wire goes under the heat shield back about 6" towards the back of the engine block on the right side of the engine.  Any help would be greatly appreciated.  I can't find anything on Porsche websites or the SRM I purchased, although SRM I have doesn't give me a good view of this for my 3.6. 

Thanks
