Hi Huds - welcome to the forum.

Sorry I have no idea what you're referring to.

A bit more info., such as engine type, etc may invite more advice.

Mostly a wiring problem on these check at terminal 3
at ignition on for a 5v feed sensor plug disconnected
terminal 1 (earth) plug connected back probing terminal 2 must read at ignition on 0.5v's at idling
this 0.5v's should read slightly over 1v Hth Regards Mickeybo
