Replacing the Oxygen Sensor on a 2002 Honda CR-V

In order to pass the New York State vehicle inspection, all emissions control components must work. For example, if the oxygen sensors fail, they must be replaced. If you ever need to replace an oxygen sensor, these instructions from the CR-V Owner’s Club help.

I bought the DENSO part 2349005 {#36531PLE003} OE-TYPE OXYGEN SENSOR from Rock Auto, after pricing the same part elsewhere. Denso is the original equipment manufacturer, so this is the same part you’ll get from Honda, for $150 to $300 less. The Honda dealer who read the code from the on-board computer wanted an arm and a leg for the part, $450, plus another $80 to change it.

However, the sensor was in so tight, and I was unable to get any leverage on it, that I ended up taking it to a shop just to get the old one removed. The mechanic there had it out, and replaced, in a jiffy, for only $25.
