O2 Oxygen Sensor - Upstream (front)

I went recently to Advance Auto parts, and they looked up with an OBD-II my car since I have a engine light poping up. The Result was that my upstream O2 Oxygen sensor is broken.

Advance Auto parts gave me a price for: (don't remember the brand) for $167.00 or a Bosch for $229.00
RockAuto Parts + $10 shipping: Bosch for $181.79 or AIRTEX Wells for $183.79

My question to you guys should I go to with Bosch or AIRTEX from RockAuto parts?
Or can any of you recommend me a different site/ brand?


Thanks,

d4rkv

I like RockAuto for general replacement/maintenance parts.  They ship fast.  You probably won't find one much cheaper elsewhere.

Re: O2 Oxygen Sensor - Upstream (front)

Theoretically they are all the same. A Corning Glass substrate with a special two metal sputtered on coating. What differs is the mounting thread, wiring and connectors, and heaters or not. Thus, I would go with the cheapest that you trust (which IMHO would preclude any made in China).

Re: O2 Oxygen Sensor - Upstream (front)

Amazon

1     "Bosch 15537 Oxygen Sensor, OE Type Fitment"
Total for this Order:       $109.04

The snap in tie wrap retainers they include will required me to drill new holes in the bracket that attaches to the coil pack.

For the price, it was well worth the "hassle".  The included copper based hi temp antiseize.


I just replaced mine last week after 100k miles on the original.  You'll need to disconnect the battery to clear the code.
The slotted O2 socket that Autozone sells works fine. I used a wrench on it to break the sensor loose, then was able to spin it out by hand.

I just did mine and didn't need to re-drill holes. I cut out the old retainers and just used zip ties to attach the new sensor wire.

That's what I did with my extension for my header, too.

I hope that works on mine, too. I don't want to drill into anything, I become a noob when it comes to this, I like plug/ play.  banghead

I guess this is the Oxygen Sensor (thanks for the tip at Amazon) http://www.amazon.com/Bosch-15537-Oxyge … amp;sr=8-1

Now I need a Crowfoot socket/ wrench and the ramps I borrowed. Can I access the Oxygen Sensor by taking off the front right wheel? Or
is it even possible through the engine bay since I have a Linear?

Stupid question but do you guys have a picture how you ziptied it?

Thanks,

Re: O2 Oxygen Sensor - Upstream (front)

No, but the ties go through the holes where the retainers are now.  It's not that hard to do.  Just make sure there's no wires on or real close to the exhaust when you're finished.

Also, I had to go underneath the car (on ramps).  I just disconnected the sensor and got it out with a crescent wrench.  If you decide to anti-seize the new one, do NOT get any goop on the sensor itself. It will ruin it.

Re: O2 Oxygen Sensor - Upstream (front)

For those of you that have already gone through this replacement, is this a good write up?

I imagine many of us are getting to the point where this is going to be an issue somewhere in the next year or so.

Re: O2 Oxygen Sensor - Upstream (front)

Yeah, that looks good to me from what I recall. 

I undid all of the wiring first, because I was worrying about mis-handling or dropping a still-good sensor, but I doubt the sequence is critical, otherwise.

Yep; that's the exact write-up I used and it was comprehensive.

Removed airbox (a 8" extension really helps), unhooked sensor plug, removed sensor wire bracket, jacked up passenger side, remove wheel, remove fender liner, then remove sensor.

I was surprised at how easy everything went. In total, it took me 1.5hrs from the time I picked up the o2 sensor removal tool at Autozone, till I returned it. The chick behind the counter was surprised I came back so quick.



*One thing that helped was removing the previous wire attachments one at a time. That way I was able to place the new zip ties at the exact same point on the new sensor, by lining up the old sensor to the new. No fiddling with figuring out the amount of slack on either side of the bracket.

Re: O2 Oxygen Sensor - Upstream (front)

Can you guys elaborate on what needs to happen with the bracket and wires and plug? Does the new sensor come with the correct electrical plug or just bare wires? Does the bracket on the coil pack actually connect electrically to something, or is it just there to hold the wires away from the exhaust? I'm having a hard time picturing what you're talking about.  TIA

Re: O2 Oxygen Sensor - Upstream (front)

The plug is a direct fit item. No bare wires or anything of that sort.

The wiring is secured to the metal bracket to keep it from flopping all over the place.  The bracket is secured by the coil fastener, but not involved with the ignition system in any way.

Re: O2 Oxygen Sensor - Upstream (front)

Just to bump this with some more info.  I have P0311 as well and have to replace the Upstream o2 sensor.  I looked around and the best price reputable dealer I found was Rock Auto at $120 shipped for the Denso.  Apparently the Denso and Bosch are identical.  So if you need to do this hop on over to RockAuto and grab one.  Also, haven't been able to find a better write-up so this should be the go to front o2 sensor thread. lol

Re: O2 Oxygen Sensor - Upstream (front)

arrow-up  I don't recall exactly how much I paid nor my Denso one, but it was a fraction (As I recall) of that, like maybe $80 for the sensor and 1/2 drive socket from Amazon.

Re: O2 Oxygen Sensor - Upstream (front)

Are you talking about the downstream o2 sensor?  Because the cheapest Amazon has is the about $110.

Re: O2 Oxygen Sensor - Upstream (front)

Shop around, I got mine for $60 not too long ago, and that is CAD, we always pay more for things. Denso Sensor.
