Hey everyone,

I've had a check engine light for like 8 months. It occured after the rattling heat shield was removed from the cat. I checked the code and it's the secondary o2 sensor. Exactly which o2 sensor is the secondary one?

My car is a 97 Integra 4 dr automatic.

Thanks!

 

The back one.

 

Correct. The back one. Closest one to your muffler or further away from your exhaust manifold.

the primary one is in the header on the ls, in the cat closer to the header on 94-99 gsr.

 

The O2 sensor closest to the front in every car is the primary,the one in the back is always secondary.
