Accord O2 sensors easy reach?

I'm asking on behalf of a friend who might want to change his O2
sensors soon. Are the connectors easy to access from underneath, or
stuffed up under the carpets somewhere?

Another question was whether we need the ULEV sensors or the cheaper
ones? When the owner got it checked they told her it is a ULEV engine.

Thanks for any tips!

ps Its the 4 cylinder model from 2001

 

There are two O2 sensors so make sure you get the correct code for the
one that is faulty. The one is located in the engine bay by the
exhaust manifold. The other one is located directly on the cat and
should be easily accessible if you have a lift. You'll need an O2
sensor socket to get either one out easily.

 

"want to change his O2 sensors"??? /why/ would they want to change
them? what code are they getting?

you could get at them from underneath the carpets, but it would be a lot
of hard work. you're better off opening the hood and looking at them
bolted to the exhaust system right in front of you. and you'll need the
correct tool.

my tip is that if you don't know what you're doing, leave well alone.

 

I'm talking about the connectors, not the sensor end. On my lexus the
connectors were buries inside the cabin under the carpets and air
ducting, and that is what took all the time. What I'm asking is
whether the connectors are easily accessible from under the car or
through the endgine bay or not.

The car has 90K miles so I thought if we change one might has well
change the other while at it.

When I replaced the second (of the two on the car) o2 sensor on my 03
Accord, the Helm manual (that's the shop manual) instructed me to remove
my front passenger's seat in order to get to the piece of carpet to move
out of the way.

However, the 02 and 03 are different generation Accords; I suggest
having the Helm manual for your car.

Yeah they said that about the lexus too, and that was BS and totally
unnecessary. I'll tell them to get the Haynes manual.

Thanks

NOT Haynes! The factory shop manual for a Honda comes from helminc.com

 

No you do not need to remove anything internally to get the O2 sensor
out of the cat. The plug is located about a foot from the sensor.

 

Excellent. What I needed to know.

Dean,

what you need to know is what is needed for your car. What I told you
applies to the 03 sedan, and is neither unnecessary nor bullshit. Nick
may be correct about the 02, but the only ways for you to know are 1.)
try it, to see what you have to do to remove it, or 2.) have the proper
reference (the shop manual) which will tell you.

Dave - I'm sorry if I was rude. It isn't my car, its my workmate's car
and I don't have time to fix it myself or even climb under it to take
a look. I just wanted to advise them on whether it was a simple car-
ramps job or if it required taking up all the carpets or seats. For
them, they'll do with the cheapy Haynes manual (personally I quite
like the Haynes, but I never seem to own a car that has one any more!)

Cheers,

No problem, Dean. I still cut corners myself, but I have found that
very often (with the Honda, at least) that the shortcuts wind up costing
me more time/money than if I had done it right the first time.

I have never used the Haynes manual for these cars; they may be fine.

Good luck with it, in any event.
