Default O2 sensor replacement

Hi all

I got my air flow meter replaced today, covered by the recall of course. However, I was advised that I need to replace the front O2 sensor, as it has a malfunctioning circuit. To do this repair would cost about $400. The car seems to run fine, and the CEL is not on. The only thing the lady mentioned is that if I don't replace it, I may not pass Air Care. So do I need to shell out the four bills for this? Christmas is coming soon and I would like to not have to spend money that I don't need to. BTW, my 3 year warranty expired this February and the 5 year warranty doesn't cover O2 sensors, apparently.

Im not quite sure, but I thought a new Bosch O2 sensor just costs about $80 something at Lordco. So if its just your O2 sensor thats malfunctioning, they are charging a lot for labor.

Oki...seems like I shouldn't get this done then. Not at this price anyway. Phew, I'm glad I brought it up.

The Subaru price for the front sensor is $111 and it takes all
of 10 minutes to change it with a 22mm wrench and a pair of
ramps. Even if you had to buy the ramps and wrench, it should
be less than $250 total, taxes in.

The front O2 sensor controls your a/f ratios so you would know
if was going bad pretty quick (rough idle, hesitation), not to
mention the half-dozen or so codes that cover it's operation. It
sounds like your garage was trying to make a buck.

sorry but aftermarket O2 sensor doesn't work good on Subaru or any Jeep models....so far as i know even Nissan....

they will take off ur CEL....but still fail air care....

if you want to risk that w/ another $150 or so (inc install and taxes)....do it at your own risk....

Specialty charges even more...

they charge my friend 7 bills for front O2 sensor replacement, replace spark plugs and diagnostic the CEL...

so now say $400 for O2....does diagnostic (1 hour) plus spark plugs replacement costed 3 bills?

This was Richmond Subaru. For parts and labour, they quoted $344.50 plus taxes. The part is $200-something, but has to be ordered and shipped from Toronto. It would be a half-hour job.

the matter of fact is does it really need to be replaced?

If it is the front, then the cost at the dealer should be in the
$120 range. They sound way high for it, even shipped from
SOC in Toronto. 1/2hr labour - $40 max. Too high for a part that
it doesn't sound like you need.

I just ordered an OEM front O2 Sensor (made by Bosch) for my 99 RS from here:

www.Drivewire.com

And it was under 55 USD.

Presumably everything goes to one central warehouse in Toronto
and then shipped out to the rest of Canada. It would of course
make sense to have a western and eastern distribution, but I
would suspect that volumes don't justify having two.

As far as how I know how much the front O2 is, I have done the
replacement myself. The front O2 is around $110-$115, but the
rear is around $250-$275. Maybe that's where the confusion is,
since the front is refered to as the "front air-fuel sensor" and
the rear is the "oxygen sensor". I also learned that one the hard
way from the parts doofus at the dealer who gave me the wrong
one the first time around. I can't find the bill right now, but I'll see
if I can dig it up and the part number too. The $120 range puts it
in line with what Peaty posted as well.

Found them:

A/F Ratio Sensor - 22791AA00A - $111.45 (a.k.a. front O2 sensor)

Sensor Assembly-Oxygen - 22690AA350 - $277.17 (rear)


These are right off the parts invoice from the dealer here in Ottawa.
The front monitors to a/f ratio which the ECU then alters
accordingly. The rear simply monitors the catalytic converter
efficiency (and trips the infamous P0420 code). You'll know fairly
quickly when the front starts going bad by the way the car is running,
but the rear plays no part in fuel delivery so if it goes bad the worse
that will happen is a CEL.

Oh okay, then the one malfunctioning in my car must be the rear, because the car runs and and only the CEL is tripped occassionally.

Can I replace the rear one myself? Or is that possible only for the front (with a 22mm wrench and a pair of ramps)?

Both are the same 22mm size and are easily replaceable with
a pair of ramps, although a slightly tighter fit to get to the
back

Actually, on second look, the report from Rmd Sub indicates that it is the front O2 sensor which has a malfunctioning circuit.
Guess it is the front then?
Or should I just replace them both?...
