How would you know if oxygen sensors need to be replaced?
Kikoaliyah
For most of us we wait until a check engine light appears and a code(s) stored in the ECM tells you which 02 sensor(s) is not functioning but, if you had the proper scanning device you can moniter the performance of each 02 sensor and determine if it is up to par or not before it sets a code.

Are oxygen sensors interchangeable?
Some are and some aren't. There are different variations of oxygen sensors. First you have narrow band and wide band O2 sensors, then you have heated and unheated O2 sensors. Unheated sensors can have 1 or 2 wires , while heated sensors can have up to 5. Also some sensors are specifically calibrated to the unit they are intended for, so unless you really know what you are doing, then no they are not interchangeable.
Why would the check engine light come on after the car has warmed upI have a 95 elantra 18Lcould this the oxygen sensors?
Mostlikely one of the O2 sensors take it into autozone if you have one and have them run the codes with a reader and they will let you know what the codes mean.

4, one in front of catalytic convertor, one behind, on each pipe. If you need one replaced, ask the worker at the auto parts store to read the code and he/she will know which one is bad by the code given.
