Should I replace my upper oxygen sensors now that Im up in the 100,00 mile range?

 

Are you throwing any CEL codes?

 

Its usually recommended to change em out every 60,000....but i have yet to meet someone that follows that "rule". I replaced mine after the check engine light pointed me towards them.

 

there is no schedule for the oxygen sensors, just replace them when they start to give you trouble (CEL, or poor mpg for no apparent reason w/o a code)

i have 115k on my factory sensors w/ no issues yet

 

Mine's got 122K and I don't believe they've ever been changed, I'd side with the "don't change until needed" people.

 

With the thought of brand new O2 sensors quality of operation compaired to 100,000+ miles 10 year old sensors quality and accuacy of opperation is hard to leave.


The BOSCH 13610 sensors are about $32 online.

The dealer ship has DENSO for $82.

 

I foun the DENSO 234-4718 for $25-$35 online.
