Can I use generic CO2 sensor, like these?

Post by **JimBee** » 20 Aug 2012, 09:01

I found a post that led me to this Amazon page:

Poster said he was happy with the 15717. I guess if it gives lamda that's all that's needed, right?

What would be the best way to splice the wires? And, are they color coded?

Volvos hate those things. Go with the direct fit sensors.

I used a Bosch 13877 sensor in the front position of the 96 850. Still working fine 10 months later.

I use end to end crimp connectors. Its more reliable than soldering.

Apparently with those sensors that do not have the direct fit plug connectors, it's all in the crimp.

Because the function of the sensor is to transmit a stable electrical signal, the connections have to be very good, and must hold up well over time after repeated sessions of extreme heat and cooling. A lot of people have trouble when they do the DIY crimping, but if you have more experience than "hey-just-crush-the-wires-in-there-really-good" then it may work for you.

For the records, there is a difference between CO2 and O2 sensors.
OK, I will keep my mouth shut before JimBee kills me LOL.

Thanks to tjts1 for the pointer on

Oh, yeah. CO2, what was I thinking? Just tired, I guess when I posted that one. At least I didn't call it genetic

I can handle corrections : )

But Erik or others, if you read this, what's the trick to making a good crimp?

I think this is the direct fit one, no crimping crap needed...

Yep, sent from my rooted, rommed Galaxy Nexus....

$55 extra just to avoid crimping 4 wires?

I didnt see that those were that cheap. I would be sure to solder the connections though, less resistance and less chance of seeing issues with the crimps

did you actually read the post before you laughed about it? Because that (in bold) is not what it says. The advice has nothing to do with avoiding wire crimping, it doesn't take much effort or brain power to crimp wires. The point is that often, crimping doesn't work with O2 sensors. If it's working for you, maybe you could give a little detail on how you did it, that might help someone ...

There have also been discussions on this on the board about soldering, again because of the conditions it is exposed to, I think soldering is even more likely to be inadequate. Just relaying what I've read, don't mean to be a killjoy ...

jimbee, I know there have been threads here about crimp techniques that work, that's about all I can come up with right now. Search, you may be able to find it.

Negative, the direct fit sensor for the front is Bosch 15097: https://www.amazon.com/Bosch-15097-Oxyge ... B000BZI3G2
