Logic of naming sensors in VW-group is simple it contains "G" (german "Geber") + sensor number. The sensor number is unique. Here you can find fitting location, connectors and pins description, some information about sensors signals.

To our mind, sensors information is reference, so there is only simple search by sensor number.



Connectors on underbody at right:


1 - G287 Lambda probe 3,

     after cat, grey,

     4-pin (not with engine code: BLY, BVZ)


2 - G130 Lambda probe bank 1,

     after cat,

     black, 4-pin


3 - G131 Lambda probe bank 2,

     after cat, brown,

     4-pin (not with engine code: BLY, BVZ)
