Quick diagnostic question...

[Caribeena]

Just cleaned my oxy sensor on my 4age blacktop, and when testing the voltages across pins found a fork going between WA and WB.
Is this normal? if not what would it achieve?
Thanks

Is that in the idagnostic box, but out to one side of it?

Pretty sure that's for the ABS system and is always there.

You have to take it out when you connect thye scan tool to do diagnosis on ABS, and re fit it again when you've finshed.

So yeah, just leave it there.

ok thanks for that, was jsut curious and didn't know if it was done from previous owner or if it was meant to be there.
Thanks
