P2801 Fault Code

[CitroenB]

Took my Berlingo van to my local garage as airbag light had come on. On hooking up he found a P2801 fault code but couldn't explain what that was. He reset the airbag light which stayed off until today when it came on after going over a small bump in the road but went off again after van being stationary. Still no idea what P2801 means on a Citroen. Any help would be much appreciated.

Not sure about the Berlingo, but on the Xantias, a cleanup of the switches under the drivers seat, usually cured the airbag light.
P2801 - Transmission Range Sensor 'B' Circuit Range/Performance (I googled this-)
