Thanks for replying Mark.

My Westy is a 1987.

I have been thinking about substituting a rheostat for the Temp II sender so that I can control that variable. I could then observe the O2 voltage as a function of the TII voltage. Perhaps more importantly I could observe the drivability as a function of TII voltage.

Has anyone solved for the resistance of the TII sensor from the observed voltage across it and correlated this with a water temperature measurement?

Joe
