I need to replace the front passenger 02 sensor in my 97 Camaro Z28. Is this the right one? Picture of o2 sensor

It's part # 25312184. Thanks.

 

For the front O2s (94-97), yes, I believe that part number is correct. (http://www.csce.uark.edu/~jgbertr/rb/Parts.htm)

 

ok and there are 4 sensors am i correct?

do all of them need to be replaced?

and where are they all located?

 

Depends on the year of LT1. Cars with dual cats ('96-'97) have 4 sensors: one before and after each catalytic converter.

 

but my 94 only has 2 sensors ?

 

correct. you have 2 heated O2 sensors in the collector of your exhaust manifolds.

 

More specifically, the reason that '96 and newer f-bodies have 4 oxygen sensors is because of the introduction of the OBD2 (a.k.a. OBDII) computer and dual catalytic converters in '96. This updated computer (PCM) has two extra sensors, one behind each cat, to monitor the health of the catalytic converters; basically to make sure the cats are doing their job. Just a tidbit of history.
