i was wondering if there was a difference in oxygen sensors between the primary and secondary oxygen sensors in the car other than the colors of the wires and the look of the sensor, like does the seconday sensor have any mechanical difference on the way the engine performs than the primary one or does it matter where you put each sensor

 

they are interchangable.

 

well i keep gettin the cel code for seconday o2 sensor n i have it plugged in, i have a 96 ex coupe with a 97 cx p2p computer and motor obviously
