Here's an interesting thread in the TB archives that includes mention of the differences between the Bosch sensor used with LH systems and the NTK sensor used with Regina
https://forums.turbobricks.com/showthread.php?t=286348 How to measure O2 signal for Regina

Seemingly a significantly different techonology used, with the zirconium Bosch generating variable voltage for the LH system while the titanium NTK design provides a variable resistance for external voltage with Regina.

Noted in that thread is measuring voltage in circuit and the slightly different operating voltage ranges for the two designs. Clearly you need a good meter to get half-accurate millivolt readings, not some $10 special. Some guy who was apparently obsessed with clean flame traps was part of that conversation (lol).

Note to the OP, Peter, regarding premature O2 sensor failure, in that thread it mentions what I was going to suggest
100,000 miles, O2 should be changed...if engine consumes oil thru exhaust pipe, it won't last long
