Yes - O2 sensors are like light bulbs they wear out over time. 60K miles
is
around the time that they will start going.
By the time the engine computer has determined an O2 sensor is bad, the
sensor has been "lazy" for a while.
-However- it is also possible to check for this. The mechanic can put a
oscilloscope (ie: engine analyzer) on each of the sensors and observe the
speed of their response to changes in the exhaust stream.
Ask the dealer to quote the job as 1 job replacing all 4 of them, or 4
separate
jobs. If the dealer is tacking on a fixed labor charge to each sensor
replacement,
why then it is going to cost the same to replace all 4 over time, or all 4
at once.
Yet, there is labor expended in getting the car into the service bay and
on
a lift
and such - so, there is a slight savings in labor to do all at one time.
If
the
dealer is willing to pass that cost along to you - it might make sense to
get
them all done now.
You might also ask if the O2 sensor is covered under the
federally-mandated
emissions warranty. Seems to me that it should be.
