My parts store lists a Bosch O2 for $31. It has a crimped on connector on the end. I am guessing this is the universal. They also list a Bosch for $78. I am guessing it's the OEM harness. Bosch usually makes good stuff and I am assuming the only difference is the connector for another $50 bucks.

Napa has an NGK for $91, another guy wants $118 for an NGK.

Question: Bosch Universal works well? I know the sensor measures very small changes in voltage, so that wire has to have a good connection. Should I solder it on?

Sounds like you're shopping at the wrong places :-/

I can pick up a new Bosch 02 sensor for $20

I picked up at Bosch direct fit for my old DX for USD$30 a couple years ago. I can't imagine they cost much more than that.

If Zach would kindly share *where*.. perhaps it would make some sense to take a quick trip across the border to pick it up.

Autozone in Parkland...and before we get nitpicky, it was $24.

Thanks guys, this is in Canada - although I can't see why it would make a difference since $Cdn is pretty much the same as $US. Anyway, I have to get this emissions test passed asap. I called around and that's the going rate for them. Even on ebay I'm not saving much. I bought the Bosch and I'm halfway through putting it in. It was only $31, plus 2 mins of time to crimp the wire.

Not bad :) Now go pass that smog test!

BTW, I like excuses to zip over the border - You can buy really cheap beer everywhere. My wife likes those factory outlet stores just north of Seattle.

This is past usefullness for the OP but, just as an FYI, sparkplugs.com have both NGK and denso universal O2 sensors(without OE plugs..solder yourself) for less than $20. If you want them with the OE plugs aready there I think its $35 and $58 respectively.

HA! Didn't realize you were just across the Straight :)

Totally OT, but have been to the shops at the Casino yet? It's just like a mini version of Caesar's Palace in Vegas.

Nope, haven't seen the Casino. Unfortunately my job posted me to Ottawa Ontario - hence having to get an emissions test and why I am replacing all these parts. The area around the straight is the most beautiful part of the world though, and we will move back one day.

Thats cheap. Even oxygensensors.com wants $38 for Denso and about the same for Bosch... But they have another generic universal for $19.



I picked up my Bosch universal one that the local NAPA for about $20. Funny how they want an extra $70 for the ones with the stock connector on it:rolleyes:

I installed the universal. Definitely get an O2 socket to do it - it's way easier. After crimping the wire onto my old harness, I put a little solder on it to make sure the connection is good and covered with heat shrink. The car drives exactly the same as far as I can tell.

I did pass me emissions test however:
HC ppm 10 (max allowed 66)
CO % 0.01 (max allowed 0.37)
NO ppm 720 (max allowed 757)
Dilution % 14.41 @ 2700 rpm, 13.91 @ idle

Previously the NO was 3350 with a faulty EGR valve. We drove the car hard for a few mins and retested to get an NO 1550. The next day, after replacing the EGR NO dropped to 920. I am guessing the O2 was making it run too lean - hence the high NO readings. However, the dilution, HC and CO readings are pretty much the same as before. I expected the NO to be a bit lower after the new O2, maybe the computer needs time to adjust. I also didn't drive the heck out of the car on the way to the shop this time - maybe that would have helped get the Cat and O2 really up to temp.

Since it was the original O2, I guess I can't complain about replacing it but I would still prefer to have the car running lean. Oh well, save the earth and all that...

I would reset the ECU and follow the manuals instructions on how to re-train it.

It is because you are a new member, I think it is a month before you can PM other members.

Dogbone? And the universal O2 is best sourced at your locate auto parts store. I have the part number somewhere....

Did Carmadillo go out of business?
Damn economy!
