Rearend temp sensors
Anybody know anything about Volvo rearend temp sensors. Every thing looks to be good wiring wise but no working. Maybe some computer sender or something. Maybe someone's already had this issue before and can give me some info.

Both of them or one?

Both are dead don't read just stay on bottom of gauge. I thought maybe corrosion at the senders at the rearends but that doesn't seem to be it.

Open the instrument cluster to check all plugs around "B"
see diagram

RE: Rearend temp sensors
I would start here
1 disconnect plugs under truck from sensors.
2 Ignition ON check with ohmmeter any voltage on both pins to the ground
TURN IGNITION OFF after this test
3 If no voltage check both pins of each plug conductivity to the ground
4 Disconnect plug in instrument cluster and check wires conductivity all the way from sensors
