Mazda 626 frm 1996 doesn't have O2 sensors, have you ECU/PCM inspected, it might have a minor damage.
I have a 1996 cadillac deville concours, an it has 4 oxygen sensors
All oxygen sensors are threaded into the exhaust system.
The oxygen sensors on a 1996 Chrysler Town and Country are screwed into the exhaust system behind the engine.
The upstream sensor is screwed into the exhaust manifold behind the engine. The downstream is screwed into the pipe after the catalytic converter.
== == 1996 Corolla's have two oxygen sensors. The first sensor, is pre catalytic converter. It is located on the exhaust manifold. The second sensor is post catalytic converter.
Oxygen sensor is on the exhaust. It controls fuel injectors, and if bad will cause "check engine" and will fail at smog test. They cost about $50. I replace them every 2 years. Right and left are determined from sitting in the drivers seat. Right is passenger in the USA.

they are part of the hub assembly
The oxygen sensors are located in the exhaust system on either side of the catalytic converter.

where is the oxygen sensor located on a 1997 Chevrolet lumina
your o2 sensors are located before and after your catallytic convertors
Two, One on the exhust manifold and the second after the CAT
Two, one before the cat, one after.
The 5.0 liter V8 has ( 4 ) oxygen sensors The 4.0 liter EFI ( which is an over head valve / pushrod design ) has ( 3 ) oxygen sensors Note: The 2 upstream oxygen sensors are used for adjusting the air / fuel ratio of the engine , the other oxygen sensor (s) are called catalyst monitors and monitor the performance of the catalytic converter(s)
It is a nonservicable part, just replace it.
