replacing oxygen sensor 99 accent

where are the oxygen sensors located.Have 66000 miles on the motor and
they haven't been replaced.Any help would be appreciated

 

motors don't have 02 sensors, engines do =-)
no one can help ya out unless you tell us what car and year u have....

 

well im a twit, just woke up .... sorry i missed what car ;P
same as ours, one is on the exhaust manifold/c converter open the hood and
on your right of it youll see it towards the side.
the other one is on the exhaust pipe behind the engine.. why do you want to
replace them? are u getting a engine light?
ours has over 100 000 miles and we still have our origional 02 sensors

 

Are you getting an Check Engine light? O2 sensors aren't replaced based on
time or mileage, only when they fail.

 

thanks for the info.Yes the engine light is on,the gas mileage has
dropped[despite tune up],and there's a strong smell of gasoline from the
car.

 

If you smell gasoline, it IS NOT the oxygen sensor. The difference from a
bad oxygen sensor will show up on a HC analyzer. The PCM will not just start
dumping gas into the cylinders. I'd suggest that you have someone
knowledgeable look at the vehicle, and figure out where the gas leak is
that's bad enough that it's affecting your mileage. It could be a leaky
injector, or many other things. If you smell gasoline, you are literally
sitting on a disaster waiting to happen.

 

Agreed, with the additional comment that if there is a strong smell of
gasoline, you should be able to see it. A car that is simply running rich
does not smell like gasoline. The only thing that smells like gasoline is,
well... gasoline - as in a leak.

 

maybye check your emissions canister....

 

Unbelievably, they - three of them - are required to be replaced on the 2006
Sonata at 45,000 mile intervals to the tune of $321 + labor unless you do it
yourself. It is an emissions warranty requirement. I just found that little
gem today on the Hyundai website.

It's not in the required maintenance section of the owners manual, so I
don't know if they can actually enforce it.

 

Man. That's a pain. I currently own my first Hyundai ('04 Sonata) and I
like the car - should say my wife likes *her* car. I know this only applies
to the'06, but it seems there's an increasing number of not-so-routine
things being required by Hyundai to maintain the warranty. Some things I
can understand, like the timing belt, although a chain would have made that
a moot point. At some point though, the maintenance being mandated by
Hyundai in order to keep the car under warranty coverage is going to hit the
point that it's more expensive to keep the warranty up than to repair any
other car.

O2 sensors should never be a warranty requirement. They don't fail at
alarming rates in cars today and Hyundai should be able to put sensors in
that are as reliable as any other manufacturer. In all of my years of
driving cars that are equipped with O2 sensors, I have only had to replace
one, and that was back in the early years.

 

I agree. I keep my maintence records in Excel and when I added in all
of the Hyundai required items, the list was nearly twice as long as my
Chevy truck and Dodge minivan. This 100,000 mile warranty may be a lot
more costly than meets the eye.

Do all Sonata's have three or just the V-6? I have the 4 cylinder.
Where do you see them having three? I didn't see the number mentioned.

Matt

 

Well, yet another area that the 4 cylinder is less expensive. Even so,
I think this is a crazy requirement and I'm planning to follow my
manual, which I don't believe called for pre-emptive replacement of the
O2 sensors.

This beckons a question - is it possible that there IS the same requirement
on, say '04's or '05's? For that matter, is this a requirement for other
models like the Elantra, or the XG350/Azera (which also happen to have the
100,000 mile warranty).

With me owning one Hyundai and one Kia (which also makes a big too-doo of
its 100,000 mile warranty), I am understandably curious.
