Vehicle speed (presuming that's what you're concerned with) sensing is a function of the ABS module using the 4x wheel speed sensors, with the result being sent to the Body Control Module over the HS-CAN bus and onwards to the instrument panel over LS-CAN. There is no physical speed sensor on the (MLGU6) gearbox.

The individual wheel speeds can be read at the ABS module and the calculated vehicle speed can be read at both the BCM and the dash module (with suitable diagnostics e.g. Diagbox).

@fawlks What year was your Citreon Relay manufactured? 

I thought older models (pre ABS) had a small pick up somewhere on the transmission, possibly near one of the driveshafts?

^^^ See thread title.  A function of the ABS module since the X250 in 2006/7.

Ooops! My bad, I normally look for such detail within the posting or signature.

Sorry @fawlks
