What Carl said to test the sensor.
I use a PT wheel in a Madone with a Duotrap with no problems but you do have to set it up. I do this:
Speed: PT (no need for a wheel magnet and it's a reliable source)
Power PT (obviously)
Cadence: Duotrap.
I can't off the top of my head think how you do it, and specific head units may be a different setup. It's a case of pairing the sensors to operate as above. I'd remove and re-pair both.
Good luck.
