O2 Sensor on Toyota Celica has gone bad. Which one do I need for my 1997?

[Ryan B]

Here is the info that came from the OBD II:
P0133
O2 sensor CKT slow response
Bank 1
Sensor 1

Provide links to a specific model and type if possible
before or after catalytic converter? heated or unheated?

Bank 1 is generic statement along with sensor 1. Since you don't have 2 banks, because the engine is a 4 cylinder, there is only 1 sensor. The o2 sensor between the exhaust manifold and catalytic converter is the one you want to replace.

You go to the auto parts store and tell them exactly what you posted here, they can look it up and give you the correct sensor.
