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.

Competitive Pricing of Substitutes in Transportation

Nate Silver has an interesting, if partial, analysis of statistics comparing modes of transportation based on the National Household Travel Survey. He wonders why Americans prefer to drive long distances than fly, and calculates the costs to be generally cheaper if one flies.

Today the Poughkeepsie Journal did the same thing for the costs of commuting by car or rail. (Unfortunately the website doesn’t include the charts.) Rail is cheaper, but the comparison leaves out the cost of time.

Both comparisons depend on a variety of factors, including, among other things, the number of passengers, the length of the trip, whether you’ll need a car to get around at your destination, the bulk and mass of your cargo, and so forth, none of which are really taken into account. For us, trips generally involve six passengers and gear. This rapidly decreases the value proposition of plane or train travel since we’re dividing the total cost by six, making our own personal mass transit more affordable.

It doesn’t help that Amtrak’s prices this year are the same as last year’s, while JetBlue’s have gone down.
