O2 Sensor - CEL light, then no light!
Posted 18 October 2003 - 08:35 PM
I'm debating whether I should take back the O2 sensor. Is it more likely that the light will come back on again, or that it was just a temporary glitch and I may go for a few years without seeing it again? Do O2 sensors have a predictable lifespan?
If anyone can see into the future, that would be really helpful.

2) Feel the bumper around the tailpipe for soot from black smoke, indicating running rich...
These signs might suggest that your O2 sensor really is bad...

A friend of mine at work was getting CELs and poor mileage in his '93 S-10. We pulled the codes and it said O2 sensor was bad. I lent him my O2 sensor socket and he replaced it in about 10 minutes. He hasn't measured the mileage yet but he thinks it has gone way up and his CEL is gone.

My 2000 did the same thing. Hard driving turns it off (detects more oxygen?) and easy driving turns it on.
2 day intervals were about right..

(86,040... last milage recorded before he 'Ru2' died)
