02 sensor........where can i fnd it

i have a zxi tegs 91 zc_1600. and i want to know where the o2 sensor is or which one is it. as i see a sensor on the exhaust and one under the car? :sad:

Look in the book
:werd:

u mean the one on the exhaust thats connected to the one under the car??? i thought that was the O2 sensor :think: :shock:

All Integra’s have an O2 sensor either in the exhaust manifold or just before the cat converter. Some have another one at the rear of the cat. The first O2 sensor helps the computer give the right amount of fuel during closed loop operation. The second O2 sensor at the rear of the cat monitors the effectiveness of the cat to lower emissions, but has no effect on how the car runs. This is all from memory, if any info is wrong, please correct me.

there are 2 O2 sensors, one is on ur headers and the other is below on the exhaust.
