Subject:      How does the Oxy Sensor Work/ go bad?

Greetings,

Can someone tell me how the Oxygen sensor actually works.  Does is work
by actually sensing oxygen in the exhaust?  Or does it "correlate" by
providing exhaust temperature to the ECU, which then interprets the
Oxygen based on other inputs from the injection system.

Does water or methanol in the fuel cause the oxygen sensor to read to
rich or lean?

Does water or methanol, or other fuel additives, cause an oxygen sensor
to fail prematurely?

Sincerely,

Mark Keller
