I'm driving a 1998 s70 GLT. The CEL light came on, and I was able to hook up a PC running OBD II software to find out there was a fault - P0172 - rich mixture from the O2 sensor. The kicker is: the car has only 62000 miles on it. O2 sensors are supposed to go bad around 100K, right?

So, I reseated the MAS connection, reset the light. The light has not come back on.

Questions:

What's normal voltage for the O2 sensors?
Do we think dead O2 sensors are a function of age or mileage?
Does my fix make sense?

Thanks,

Josh
