My Ride: BMW Z4
Z4 SMG Selection Angle Sensor fault

I need some help. I recently did a lot of work to my SMG including replacing the gear position sensor. I have the tranny reprogrammed, but I am still getting a "selection angle sensor (gear position sensor) short circuit to positive" fault. I have cleared the faults and it keeps coming back. The car runs fine, shifts through all of the gears normally, doesn't skip gears.

So, could I have installed it wrong? It can't be plugged in wrong, but could it be misaligned? It seemed pretty straight forward in it's installation, but did it need to be aligned some special way that I'm not aware of? The other sensor I replaced (shift sensor) is testing fine, no errors. Or is it most likely just a bad sensor? Any other ideas to try would be greatly appreciated!

Check the wireing for any damages at first.

If it shifts normally both sensors should work.
