Alfa 156 2,0 JTS lambda problem

Does anyone know what should be the precat lambda values for 2.0 JTS engine.
Mine is showing errors that the lambda voltage is too high.
On cold engine one lamda showing value 1500 mv and other 3000 mv.
On warm engine they are both around 3000 mv but still not the same.
Are those values normal. I guess not because it also shows error codes.
Anyway I`m using Unidiag to see those values.
