Location of the O2 sensor for a P0141
 

I have a P0141 error code and which O2 sensor do I replace for a Civic 2000CX?

#8 or #9? (see pic).

I'm thinking of replacing it with a non-universal Bosch or NKT/NKG O2 sensor.

Any comments?

According to the factory Helms service manual, P0141 is the secondary O2 sensor. So that would be #9.

Thanks. Is that a pre-cat or post-cat O2 sensor?

It's secondary, therefore after.
