Where is the O2 sensor located on a 1988 prelude si?

On a 1988 Honda Prelude Si, the oxygen (O2) sensor is typically located in the exhaust manifold or just after it in the exhaust pipe. It is positioned upstream of the catalytic converter, where it can effectively measure the oxygen content in the exhaust gases. To access it, you may need to lift the vehicle and possibly remove some components for better visibility. Always consult the vehicle's service manual for specific instructions and location details.
