Here you''ll find how to test an automotive O2 or Oxygen sensor. Automotive O2 Oxygen Sensor Testing Procedures. MAIN ... The O2 sensor must cycle at least once per second, which would show 3 cross counts on the scan tool PID. 7) Silicone is the leading cause of O2 contamination. 8) It is easier for an O2 sensor to go from rich to lean than viseversa. 9) O2 sensors tend to fail on rich bias ...

20141221· The front oxygen sensor on the GM engines is a onewire sensor, which means that it doesn''t have an internal heater. The oxygen sensor''s performance can be easily tested with a multimeter. In other words, you don''t need a scan tool with live data capability to see if the front oxygen sensor is working or not.
