The primary oxygen sensor is located before the catalytic on most Hondas depending on the year. If your Honda has the catalytic converter integrated to the exhaust manifold then you should find it on the manifold just before the catalytic converter.

How do you replace oxygen sensor Honda Civic?

If you open the hood of your Honda Civic, most likely you will locate the oxygen sensor (O2) mounted in the exhaust manifold, above the exhaust pipe flange. On some models the exact location might vary, but you can always find the sensor by following the exhaust manifold and pipe. Depending on the year model of your Honda Civic, you may find a Primary Oxygen Sensor (PHO2) right before the catalytic converter and a Secondary Oxygen Sensor (SHO2) right after the catalytic.
