Problem after ABS sensor replacement

Hello brain trust.

I’ve recently replaced my ABS sensor as part of a hub rebuild. The ABS light is still on since. The OBD just says “intermittent ABS sensor”.

The existing ABS sleeve (still in situ) is brass/copper coloured and the one that came with the new sensor is steel.

Would the material of the sleeve make any difference before I crack the hub to replace it?

Cheers all.

Are you able to read live data on your obd? If so pull up all for corners and move at roughly five mph and see what data you get , that will tell you what each corner is reading and also show a corner at fault
