Weird O2 sensor readings 700 1991

posted by  someone claiming to be ibs740 on  Wed Mar 3 01:28 CST 2004 [RELATED]

Hi: I just checked my O2 sensor after a fault code (O2 sensor). What I found was the sensor heater is OK,but the signal output is odd.
The signal once up to operating temperature cycled between 60-90 mV. This is about 1/10 of what I would expect.
Just pitch it or does this indicate it has deposits built up on it?
Any info. welcome.

Thanks IBS740 91 740 T wgn
