Replacing Oxygen Sensor.

I'm going to try and replace my O2 sensor that came up bad during
diagnostics, and my tabs are already expired. I understand there are
two O2 sensors on my model: Honda Accord 98 EX 4Cyc Vtec.

Is this something the average joe can locate and replace, or do I need
to take in into the shop?

Many thanks,

--TJ

One sensor is upstream of the cat converter (= pre cat); the
other is downstream (= post cat). Find out which one it is.
Then look at parts drawings at bkhondaparts.com to help find
it.

On many Hondas these are easy to replace. You can borrow an
Oxygen sensor wrench from Autozone for a returnable deposit.
I recommend doing so. Also, buy a can of the penetrating oil
"PB Blaster" at Autozone or Wal-Mart or similar. Soak the
threads region of the O2 sensor for an hour before trying to
remove it. It might help if the auto is a little warm when
you actually try to unscrew the sensor. Be careful not to
burn yourself.

Best prices I have found for OEM O2 sensors:
automedicsupply.com . Cost you about $170 for the pre cat.
$75 for post cat. Ball park.

Only buy OEM for this part.

I can't find a diagram of an O2 sensor on their website, maybe using a
different term?

After putting your car's identifying info in at
www.bkhondaparts.com , do a "list all." Click on "exhaust
manifold." The pre cat one appears. Click on "exhaust pipe"
for the post cat one.

These sites are a little tricky to navigate at first.
Persist. :-)

Another option, go to the Parts Dept. at your local Honda dealer, have
them look up your part and ask the guy/gal to print out that page. I've
done this a couple of times and the printouts have good resolution.

Do you know how many Honda dealer parts departments now
provide illustrations free online?

bkhondaparts.com is likely one of dozens or even hundreds at
this point.

Right, but the printouts have better resolution in my experience.

At some online sites, the resolution is indeed poor. At
others, it's good. I would not count on dealer parts
printouts to necessarily be superior.

Based on my experience, so far, so good. I tossed it out as an option,
not a directive.
