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.


  1. it is a common problem with most of the mechanics at Honda care as they are not well versed with the car and sometimes not able to do anything. They are not able to solve major problems. I do not know from where do they bring in those guys for work. I mean my air filter was perfectly fine and they replaced it saying it was damaged, and also charged my $200. what on earth they were thinking.

  2. I went to my local NTB [hudson ,oh] for a ‘check engine light’. I got charged $100 for them to tell me I had a bad o2 sensor. they wanted $300 for the part plus installation. Also recommended a fuel system ‘tune up’. the total was over $500! these guys are rip off artists. they overcharge for parts & labor. Many auto parts stores will scan for fault codes FREE of Charge. Stay away from NTB if possible.
    I paid the $100 for the ‘diagnostic’ [had no choice]and told them I would never return. also…During an oil change these are the guys that drained the tranny fluid and added 5 quarts of engine oil to our subaru outback. Almost ruined the engine & tranny!
