2004 Venture Knock Sensor 1 Location?

[Tectron]

I'm getting a PO327 Code (Knock Sensor 1 Circuit Low Input) And would like to swap out the sensor, Does anyone know where this sensor is located? The code implies that there is more than one so I don't want to change the wrong one accidentally.

Thanks

Thanks, that sounds easy to get to, I was afraid it would be stuffed away in some hard to access location.
