O2 Sensor

I have a 95 Honda Civic Ex Coupe with 134000 miles. I was wondering, is it hard to change the o2 sensor on this car. I don't know much and wanted to know if I can do it myself. If I can, can someone give me the steps on how to do it.

It's pretty easy. It is screwed into the exhaust manifold right next to the radiator. Crack it loose then spray it with WD-40 real well. Then finish removing it. Should be able to use a 22mm wrench to remove it.

Some use nuts(12 mm?)to hold them in.I strongly suggest a factory Honda replacement O2 sensor to avoid problems.

My son had a '95 Ex that we replaced the O2 sensor actually twice. The first one a OEM Honda went bad I surmise because he painted the air intake tubes and I think the fumes ruined the 2 month old sensor. A ck lite with an O2 code was set in about 10 miles after the paint job. Sensor would not produce any voltage.

Honda wouldn't warrantee the sensor, so we bought one from NAPA. It was about $60 less and was the same Nippondenso sensor.

Good info on the sensor as long as a cheap house brand isn't used.I've seen those cause more problems than enough.
