I searched and found nothing related to my concern.
I need to replace my rear heated O2 sensor on my 95 S14.
The question is what is the difference between the A/T and the M/T sensor?
Since I have a A/T to 5spd swap.
Is it the thread pattern or does the ECU look for a different "signal/voltage" from the O2 sensor.
I accidently got a 24062 (for a 200SX :smash:)
Thanks in advance.

The rear O2 sensor is not sued for anything except OBD monitoring. All '95-'96 models use the same 3wire unit, small bung.

'97-'98 models use the standard large size bung, with a 4wire sensor.

There is no difference between auto and manual for the rear sensor. For the front, some late model '95 autos use the 3wire unit versus the 1wire found on most other '95s. A quick look will tell you though.
