codes 22 and 32

[markyboy]

right following on from the 4ws fault it used to flash the code for the rear wheel steering speed sensor, we changed the sensor and loom as it all comes built up and we also had to drop the gearbox sump and valve body as the plugs went through to various sensors inside the box as well but it worked and we no longer have that fault code, we do now how ever have codes 22 and 32 which i think are the front and rear steering angle sensors.
now i think i read somewhere that they have to be synchronised so does anyone know how you do that? also the steering wheel is about 45 degrees out would this have any effect on the sensor at all.
any help is much appreciated!
