AEM AFR Wideband gauge stuck on 14

I have an AFR gauge that reads around 14 all the time, reading other threads this seems to point to the wiring being broke somewhere rather than a faulty sensor. Is that right or could it be the sensor?

 

There is a youtube video of someone showing you how to test it using brake cleaner, but mine doesnt react in the same way as his example faulty sensor which again points to the wiring.

 

I want to sell it as its off the car and i dont use it but need to fix it first.

 

Any thoughts?
