Depends on what the problem is or what code was set.
When a O2 sensor goes bad the check engine light will illuminate. The code set in the ecm will lead you to which O2 sensor is bad.
the exhaust, where every o2 sensor is
The upstream O2 sensor is mounted in the ehxaust manifold The downstream O2 sensor is mounted in the exhaust pipe after the catalytic converter
The O2 sensor can be found on the outside of the air cleaner housing. The O2 sensor will be attached to the back of the air cleaner housing.
The upstream O2 sensor is mounted in the ehxaust manifold The downstream O2 sensor is mounted in the exhaust pipe after the catalytic converter
There is no fuse for the O2 sensor.
Where is the O2 sensor on 1993 Toyota Mr2
Remove the vacuum hose from the O2 sensor. Remove the wiring harness. Remove the O2 sensor retaining screws. Reverse the process to install the new O2 sensor.

A bad O2 sensor could cause the engine to overcompensate for what it believes to be a problem. It will tell the engine to let in more or less O2 and could damage the engine in the long run. The sensor is not too expensive to replace and could save you LOTS of money in the future.
