I have a PLX Wideband that's reading rich even when its disconnected. Any Ideas or do I need to just buy a new one?

 

Thats cause its reading 0.0 Volts which is rich. nothing is wrong with it.

 

no it just reads 11.2 not matter what. It did this one day going from that to lean then it just stopped really moving. So I bought a new o2 not thinking to check and same results. I can disconnect the WB and it'll still read 11.2.
