is there any way to confirm it is the module before I start throwing money at it?

As the symptoms the same as failed sensor or its wiring to module there is no way to test it on 100% certainty. Though you can measure the sensor line via module wiring connector to rule that out. There are instructions for this on similar threads on this forum.
