"Why the hell are the no test values about Regina o2 sensors anywhere?"

Hi Barry,
Google on "Titania O2 sensor" for a lot of interesting background but little solid tech info. For that you need Volvo "Green Book" TP 31903/1 for "Fuel system Regina and Ignition system Rex". Mine was $29.15 about 7 years ago.

For O2 output checking it has no cold spec (does Bosch?) but says to start the engine and put meter between the signal line ("one pole connector") and ground.
Meter should vary between 0.1V and 1.2V. Then it gives some possibilities depending on an abnormal out put.

It also shows a drawing of an OK sine wave for those values, with equal flat-topped peaks and valleys.

"Frick'n O/2 sensor..."
There's been no history here (6+ years for me) of ANY Regina O2 problems. If yours is bad, I'd wonder if it's cause of (or due to) to the glowing manifold and cooked cat mentioned earlier.
