Are these "cut and splice" oxygen sensors any good?http://cgi.ebay.ca/ws/eBayISAPI.dll?...link:middle:ca

 

I never got an answer to this.......
Appreciate some opinions.

 

I would say BS!!!.

The FRONT and REAR sensors are NOT the same. If you have to use this statement to sell stuff,,,,,,,,,,,,,,,,,,,,,your desperate!

"We use foam peanuts to pack most items. This foam is approx $0.35 per ounce cost so it adds up fast. This is the safest material other than factory packing to ship an item, so it is well worth the expense since it insures your package will arrive safely.
"

Real live sensors at AUTOZONE, with connectors and a warranty are NOT that expensive.

I am not impressed with electrical splices especially when used in brutal environments. Exhaust systems meet my definition of a brutal service environment. Wire conducts heat very well so that means the splices will have to be up to the task. Look at what happens to any electrical junction under the hood of your car.

Find out who makes the splices. Go to the splice manufacturer's web site and determine design limits for that particular piece. Just because it is a good splice inside the house does not mean it can survive the brutal environment associated with the exhaust.

If the difference is lead length how long are the pigtails on the e-Bay replacement?

Examine or ask what the differences in O2 sensors provided by GM are. There may be electrical differences, lead length differences, part body dimension differences. As much as it seems Detroit enjoys making multiple oddball parts that perform the same task, the Detroit bean counters will brutalize any engineer caught that does not re-utilize an existing part design. So if the two parts are different there is a usually a DAMN GOOD reason.

Also question the source of the parts provided. They could be new part overruns from the actual part vendor who makes components for GM or they could be back channel seconds. If at all possible check the pedigree.

Above all be careful with the part selection. This is not your Father's Oldsmobile.

YMMV

I would never splice any engine control sensor EVER. Just replace it. I have had excellent luck with Autozone sensors.

 

Thanks all.

 

Also, o2 sensors have to have a vent to ambient air to operate properly. They use the wiring itself as the vent, utilizing the space between the sheath and the actual wire. This vent has the potential to become compromised by splicing.

 

I used them on my Porsche. It's been working find for about 8 months now.

However, I live in CA and don't see the same weather conditions you do. I used crimp butt splice's and taped over them.

 

The corvette rear sensors are MAINLY different in the type of heating element they run. For what its worth, Im currently running The REAR 02's UP FRONT. and ive ran the normal ones up front also. With NO changes VIA pcm.

this is interesting as an oxygen sensor is by far a pretty universal part that has been overhyped with "oe specific jumbo" paying like 125 for each sensor sucks. If these would work and give accurate numbers then this could be a very nice option IMO.

Repair shops use these allot via Bosch with no issues if you wire it up right.

the way Long tube cars seem to cook 02's with heater codes requiring replacemnt often, If these wold work i would totally try them just soldier all wires correctly.
