How long do Oxygen Sensors last ?

Just wondering...
I know mine were probably due at 130.4K km / 81K miles at almost 10-years old

I had to have mine changed today.

How do you know when it's bad? SES light?
130k miles and still good.

My GA is in a garage right now getting repaired.

I got a SES light on.

See: SES light & Codes: P1665, P0141, P0135, P1676 (http://www.grandamgt.com/forum/showthread.php?t=70190)

The garage called me back this morning, & said I needed both O2 sensors changed.

PS: How have you been Yun ?
Haven't really seen you on the forum much, since the days of chat...

just because your SES light isnt on doesnt mean that your o2 sensors are working properly... it just means that they arent BAD ENOUGH yet to set off the SES light...

i dont know molson, i coulda sworn i heard this somewhere:
theres 2 things you should always stick with from GM, fuel filters and O2 sensors....

who told you that? Esp with fuel filters, you can get better quality at times with aftermarket, and at the price, change them annually.

Pre cat, I have a NGK and it's been fine. The post cat sensor went bye bye for a Sim. No codes or A/F issues.

thats interesting^, does one go out faster than the other really?

I'd assume the front would go out first, seeing as it gets hit with raw exhaust. The downstream gets the catalytic exhaust that's had a lot of the crud burned out of it.

FYI, the downstream sensor is there just to read the signal difference from the front one. It just acts as a tool to tell if you're cat is good or bad. It's not important like the front one.
